Allegheny County owns and maintains the Greater Pittsburgh
Airport at a site it acquired to provide airport facilities under
the Federal Airport Act. In one approach zone or path of glide, the
pattern of flight established by the Civil Aeronautics
Administrator for aircraft landing at and departing from the
Airport requires aircraft to fly regularly and frequently at very
low altitudes over petitioner's residential property. The resulting
noise, vibrations and danger forced petitioner and his family to
move from their home.
Held: the County has taken an air easement over
petitioner's property for which it must pay just compensation as
required by the Fourteenth Amendment. Pp.

MR. JUSTICE DOUGLAS delivered the opinion of the Court.
This case is here on a petition for a writ of certiorari to the
Supreme Court of Pennsylvania which we granted (366 U.S. 943)
because its decision (402 Pa. 411, 168 A.2d 123) seemed to be in
conflict with
United States v. Causby, 328 U.
S. 256. The question is whether respondent
Page 369 U. S. 85
has taken an air easement over petitioner's property for which
it must pay just compensation as required by the Fourteenth
Amendment.
Chicago, B. & Q. R. Co. v. Chicago,
166 U. S. 226,
166 U. S. 241.
The Court of Common Pleas, pursuant to customary Pennsylvania
procedure, appointed a Board of Viewers to determine whether there
had been a "taking," and, if so, the amount of compensation due.
The Board of Viewers met upon the property; it held a hearing, and
in its report found that there had been a "taking" by respondent of
an air easement over petitioner's property and that the
compensation payable (damages suffered) was $12,690. The Court of
Common Pleas dismissed the exceptions of each party to the Board's
report. On appeal, the Supreme Court of Pennsylvania decided, by a
divided vote, that if there were a "taking" in the constitutional
sense, the respondent was not liable.
Respondent owns and maintains the Greater Pittsburgh Airport on
land which it purchased to provide airport and air-transport
facilities. The airport was designed for public use in conformity
with the rules and regulations of the Civil Aeronautics
Administration within the scope of the National Airport Plan
provided for in 49 U.S.C. § 1101
et seq. By this Act, the
federal Administrator is authorized and directed to prepare and
continually revise a "national plan for the development of public
airports." § 1102(a). For this purpose, he is authorized to make
grants to "sponsors" for airport development. §§ 1103, 1104.
Provision is made for apportionment of grants for this purpose
among the States. § 1105. The applications for projects must follow
the standards prescribed by the Administrator. § 1108.
It is provided in § 1108(d) that:
"No project shall be approved by the Administrator with respect
to any airport unless a public agency holds good title,
satisfactory to the Administrator, to the landing area of such
airport or the site therefor, or gives assurance satisfactory
Page 369 U. S. 86
to the Administrator that such title will be acquired."
The United States agrees to share from 50% to 75% of the
"allowable project costs," depending, so far as material here, on
the class and location of the airport. § 1109.
Allowable costs payable by the Federal Government include "costs
of acquiring land or interests therein or easements through or
other interests in air space. . . ." § 1112(a)(2).
Respondent executed three agreements with the Administrator of
Civil Aeronautics in which it agreed, among other things, to abide
by and adhere to the Rules and Regulations of CAA and to "maintain
a master plan of the airport," including "approach areas." It was
provided that the "airport approach standards to be followed in
this connection shall be those established by the Administrator";
and it was also agreed that respondent "will acquire such easements
or other interests in lands and air space as may be necessary to
perform the covenants of this paragraph." The "master plan" laid
out and submitted by respondent included the required "approach
areas"; and that "master plan" was approved. One "approach area"
was to the northeast runway. As designed and approved, it passed
over petitioner's home, which is 3,250 feet from the end of that
runway. The elevation at the end of that runway is 1,150.50 feet
above sea level; the door sill at petitioner's residence, 1,183.64
feet; the top of petitioner's chimney, 1,219.64 feet. The slope
gradient of the approach area is as 40 is to 3,250 feet, or 81
feet, which leaves a clearance of 11.36 feet between the bottom of
the glide angle and petitioner's chimney.
The airlines that use the airport are lessees of respondent, and
the leases give them, among other things, the right "to land" and
"take off." No flights were in violation of the regulations of CAA,
nor were any flights
Page 369 U. S. 87
lower than necessary for a safe landing or take-off. The planes
taking off from the northeast runway observed regular flight
patterns ranging from 30 feet to 300 feet over petitioner's
residence; and, on let-down, they were within 53 feet to 153
feet.
On take-off, the noise of the planes is comparable "to the noise
of a riveting machine or steam hammer." On the let-down, the planes
make a noise comparable "to that of a noisy factory." The Board of
Viewers found that
"The low altitude flights over plaintiff's property caused the
plaintiff and occupants of his property to become nervous and
distraught, eventually causing their removal therefrom as
undesirable and unbearable for their residential use."
Judge Bell, dissenting below, accurately summarized the
uncontroverted facts as follows:
"Regular and almost continuous daily flights, often several
minutes apart, have been made by a number of airlines directly over
and very, very close to plaintiff's residence. During these
flights, it was often impossible for people in the house to
converse or to talk on the telephone. The plaintiff and the members
of his household (depending on the flight, which, in turn,
sometimes depended on the wind) were frequently unable to sleep,
even with ear plugs and sleeping pills; they would frequently be
awakened by the flight and the noise of the planes; the windows of
their home would frequently rattle, and, at times, plaster fell
down from the walls and ceilings; their health was affected and
impaired, and they sometimes were compelled to sleep elsewhere.
Moreover, their house was so close to the runways or path of glide
that, as the spokesman for the members of the Airlines Pilot
Association admitted, '[i]f we had engine failure, we would have no
course but to plow into your house.'"
402 Pa. 411, 422, 168 A.2d 123, 128-129.
Page 369 U. S. 88
We start with
United States v. Causby, supra, which
held that the United States, by low flights of its military planes
over a chicken farm, made the property unusable for that purpose,
and that therefore there had been a "taking", in the constitutional
sense, of an air easement for which compensation must be made. At
the time of the
Causby case, Congress had placed the
navigable airspace in the public domain, defining it as "airspace
above the minimum safe altitudes of flight prescribed" by the CAA.
44 Stat. 574. We held that the path of the glide or flight for
landing or taking off was not the downward reach of the "navigable
airspace." 328 U.S. at
328 U. S. 264.
Following the decision in the
Causby case, Congress
redefined "navigable airspace" to mean
"airspace above the minimum altitudes of flight prescribed by
regulations issued under this chapter, and shall include airspace
needed to insure safety in take-off and landing of aircraft."
72 Stat. 739, 49 U.S.C. § 1301(24). By the present regulations,
[
Footnote 1] the "minimum safe
altitudes" within the meaning of the statute are defined, so far as
relevant here, as heights of 500 feet or 1,000 feet, "[e]xcept
where necessary for takeoff or landing." But, as we said in the
Causby
Page 369 U. S. 89
case, the use of land presupposes the use of some of the
airspace above it. 328 U.S. at
328 U. S. 264.
Otherwise, no home could be built, no tree planted, no fence
constructed, no chimney erected. An invasion of the "superadjacent
airspace" will often "affect the use of the surface of the land
itself." 328 U.S. at
328 U. S.
265.
It is argued that, though there was a "taking," someone other
than respondent was the taker -- the airlines or the CAA acting as
an authorized representative of the United States. We think,
however, that respondent, which was the promoter, owner, and lessor
[
Footnote 2] of the airport,
was, in these circumstances, the one who took the air easement in
the constitutional sense. Respondent decided, subject to the
approval of the CAA, where the airport would be built, what runways
it would need, their direction and length, and what land and
navigation easements would be needed. The Federal Government takes
nothing; it is the local authority which decides to build an
airport
vel non, and where it is to be located. We see no
difference between its responsibility for the air easements
necessary for operation of the airport and its responsibility for
the land on which the runways were built. Nor did the Congress,
when it designed the legislation for a National Airport Plan. For,
as we have already noted, Congress provided in 49 U.S.C. § 1109 for
the payment to the owners of airports, whose plans were approved by
the Administrator, of a share of "the allowable project costs"
including the "costs of acquiring land or interests therein or
easements through or other interests in air space." § 1112(a)(2). A
county that designed and constructed a bridge would not have a
usable facility unless it had at least an easement over the land
necessary for the
Page 369 U. S. 90
approaches to the bridge. Why should one who designs,
constructs, and uses an airport be in a more favorable position so
far as the Fourteenth Amendment is concerned? That the instant
"taking" was "for public use" is not debatable. For respondent
agreed with the CAA that it would operate the airport "for the use
and benefit of the public," that it would operate it "on fair and
reasonable terms, and without unjust discrimination," and that it
would not allow any carrier to acquire "any exclusive right" to its
use.
The glide path for the northeast runway is as necessary for the
operation of the airport as is a surface right of way for operation
of a bridge, or as is the land for the operation of a dam.
See
United States v. Virginia Electric Co., 365 U.
S. 624,
365 U. S. 630.
As stated by the Supreme Court of Washington in
Ackerman v.
Port of Seattle, 55 Wash. 2d
400, 401, 413,
348 P.2d
664, 671, " . . . an adequate approach way is as necessary a
part of an airport as is the ground on which the airstrip, itself,
is constructed. . . ." Without the "approach areas," an airport is
indeed not operable. Respondent, in designing it, had to acquire
some private property. Our conclusion is that, by constitutional
standards, it did not acquire enough.

Footnote 1]
Regulation 60.17, entitled "Minimum safe altitudes,"
provides:
"
Except when necessary for take-off or landing, no
person shall operate an aircraft below the following
altitudes:"
"(a)
Anywhere. An altitude which will permit, in the
event of the failure of a power unit, an emergency landing without
undue hazard to persons or property on the surface;"
"(b)
Over congested areas. Over the congested areas of
cities, towns or settlements, or over an open-air assembly of
persons, an altitude of
1,000 feet above the highest
obstacle within a horizontal radius of 2,000 feet from the
aircraft. . . ."
"(c)
Over other than congested areas. An altitude of
500 feet above the surface, except over open water or sparsely
populated areas. In such event, the aircraft shall not be operated
closer than 500 feet to any person, vessel, vehicle, or structure.

See Burton v. Wilmington
Parking Auth., 365 U. S. 715.
MR. JUSTICE BLACK, with whom MR. JUSTICE FRANKFURTER concurs,
dissenting.
In
United States v. Causby, [
Footnote 2/1] the Court held that, by flying its
military aircraft frequently on low landing and takeoff flights
over Causby's chicken farm, the United States had so disturbed the
peace of the occupants and so frightened the chickens that it had
"taken" a flight easement from Causby for which it was required to
pay "just compensation" under the Fifth Amendment. Today, the
Page 369 U. S. 91
Court holds that similar low landing and take-off flights,
making petitioner Griggs' property, "undesirable and unbearable for
. . . residential use," constitute a "taking" of airspace over
Griggs' property -- not, however, by the owner and operator of the
planes, as in
Causby, but by Allegheny County, the owner
and operator of the Greater Pittsburgh Airport, to and from which
the planes fly. Although I dissented in
Causby because I
did not believe that the individual aircraft flights "took"
property in the constitutional sense merely by going over it, and
because I believed that the complexities of adjusting atmospheric
property rights to the air age could best be handled by Congress, I
agree with the Court that the noise, vibrations and fear caused by
constant and extremely low overflights in this case have so
interfered with the use and enjoyment of petitioner's property as
to amount to a "taking" of it under the
Causby holding. I
cannot agree, however, that it was the County of Allegheny that did
the "taking." I think that the United States, not the Greater
Pittsburgh Airport, has "taken" the airspace over Griggs' property
necessary for flight. [
Footnote
2/2] While the County did design the plan for the airport,
including the arrangement of its takeoff and approach areas, in
order to comply with federal requirements, it did so under the
supervision of and subject to the approval of the Civil Aeronautics
Administrator of the United States. [
Footnote 2/3]
Congress has, over the years, adopted a comprehensive plan for
national and international air commerce, regulating in minute
detail virtually every aspect of air transit -- from construction
and planning of ground facilities to
Page 369 U. S. 92
safety and methods of flight operations. [
Footnote 2/4] As part of this overall scheme of
development, Congress, in 1938, declared that the United States has
"complete and exclusive national sovereignty in the air space above
the United States," [
Footnote 2/5]
and that every citizen has "a public right of freedom of transit in
air commerce through the navigable air space of the United States."
[
Footnote 2/6] Although, in
Causby, the Court held that, under the then existing laws
and regulations, the airspace used in landing and take-off was not
part of the "navigable airspace" as to which all have a right of
free transit, Congress has since, in 1958, enacted a new law, as
part of a regulatory scheme even more comprehensive than those
before it, making it clear that the "airspace needed to insure
safety in take-off and landing of aircraft" is "navigable
airspace." [
Footnote 2/7] Thus,
Congress has not only appropriated the airspace necessary for
planes to fly at high altitudes throughout the country, but has
also provided the low altitude airspace essential for those same
planes to approach and take off from airports. These airspaces are
so much under the control of the Federal Government that every
take-off from, and every landing at
Page 369 U. S. 93
airports such as the Greater Pittsburgh Airport is made under
the direct signal and supervisory control of some federal agent.
[
Footnote 2/8]
In reaching its conclusion, however, the Court emphasizes the
fact that highway bridges require approaches. Of course they do.
But if the United States Highway Department purchases the
approaches to a bridge, the bridge owner need not. The same is true
where Congress has, as here, appropriated the airspace necessary to
approach the Pittsburgh airport as well as all the other airports
in the country. Despite this, however, the Court somehow finds a
congressional intent to shift the burden of acquiring flight
airspace to the local communities in 49 U.S.C. § 1112, which
authorizes reimbursement to local communities for "necessary"
acquisitions of "easements through or other interests in air
space." But this is no different from the bridge approach argument.
Merely because local communities might eventually be reimbursed for
the acquisition of necessary easements does not mean that local
communities must acquire easements that the United States has
already acquired. And where Congress has already declared airspace
free to all -- a fact not denied by the Court -- pretty clearly it
need not again be acquired by an airport. The "necessary" easements
for which Congress authorized reimbursement in § 1112 were those
"easements through or other interests in air space" necessary for
the clearing and protecting of "aerial approaches" from physical
"airport hazards" [
Footnote 2/9] --
a duty explicitly placed on the local communities by the statute (§
1110) and by their contract with the Government.
Page 369 U. S. 94
There is no such duty on the local community to acquire flight
airspace. Having taken the airspace over Griggs' private property
for a public use, it is the United States which owes just
compensation.
The construction of the Greater Pittsburgh Airport was financed
in large part by funds supplied by the United States as part of its
plan to induce localities like Allegheny County to assist in
setting up a national and international air transportation system.
The Court's imposition of liability on Allegheny County, however,
goes a long way toward defeating that plan because of the greatly
increased financial burdens (how great one can only guess) which
will hereafter fall on all the cities and counties which, until now
have given or may hereafter give support to the national program. I
do not believe that Congress ever intended any such frustration of
its own purpose.
Nor do I believe that Congress intended the wholly inequitable
and unjust saddling of the entire financial burden of this part of
the national program on the people of local communities like
Allegheny County. The planes that take off and land at the Greater
Pittsburgh Airport wind their rapid way through space not for the
peculiar benefit of the citizens of Allegheny County, but as part
of a great, reliable transportation system of immense advantage to
the whole Nation in time of peace and war. Just as it would be
unfair to require petitioner and others who suffer serious and
peculiar injuries by reason of these transportation flights to bear
an unfair proportion of the burdens of air commerce, so it would be
unfair to make Allegheny County bear expenses wholly out of
proportion to the advantages it can receive from the national
transportation system. I can see no justification at all for
throwing this monkey wrench into Congress' finely tuned national
transit mechanism. I would affirm the state court's judgment
holding that the County of Allegheny has not "taken" petitioner's
property.
