(l) The type balloon to be used in this phase of the project
will be a 15 to 40 ft. diameter plastic balloon, ~drogen
filled. Radio equipment weighing approximately 25 lbs.,
will be suspended approximately 100 ft. below the
balloon. The balloon will be towed to high altitude.
levels (above 20,000 feet) by three auxilliary lifting
balloons fastened together with a 4 lb. weight. All
equipment attached to the balloon will be equipped with
parachute device so that upon separation from the balloon,
the attached equipment will float down towards the earth
rather than become a freely falling body. Upon attaining
the desired altitude, the auxilliary lifting balloons
will be released from the main balloon.
(2) It is anticipated that a maximum of ten flights will be
required in this phase of operation, 2 to 5 releases to
be made from Allentown, Pa. and 2 to 5 releases to be
made from Lakehurst, N. J. Release will be made during
weather conditions in which the sky is free of clouds
and the visibility at least three miles at all altitudes
up to 20,000 feet.
(3) The range of flight during this phase of operation will
be between 30,000 and 60,000 feet. A period of six hours
will be the maximum duration of flight.
(4) New York University will provide an operator for tracking
of the balloon during period of flight and will furnish
information on its position to the N.Y. Air Traffic
Control Center during period of tlight.
(5) New York University will file a Notice to Airmen at
least twelve (12) hours in advance of balloon release and
a second notice will be filed at time of release with
either the Allentown, Pa. or Lakehurst, N.J. Communica-
tions Stations.
(6) Destruction of the balloon will be predetermined to be
effected over we.ter where hazards are not present. .Aerial
convoy will not be effected during this phase of operation
inasmuch as balloon flights will be conducted in excess
of' 20,000 feet.
3. The Vfar Department member requests that balloon operations along
the lines of Phase II be presented to the Washington Subcommittee for
clearance with all other Regional Airspace Subcommittees, in consideration
of War Department plans to continue the Pha:se II type of operation from
White Sands, New Mexico, upon completion of the 12 proposed releases
described herein. The type of balloon releases proposed out of White Sands,
N. Mex., will involve flight through other regions.
