INTEROFFICE MEMO
G.nerel William 3. Donovan E: 4 11017Wd631:ing
London Desk-4t.x.
Plasle Manufactured by Budd Manufacturing Company
am forwarding to you, at the request of Mr
A. M. Burden, the attached data on plane manufactured by the
Budd Manufacturing Company which Mr* Burden furnished me for
use of our London Office.
labia covering letter, dated 2 November 1943, Mr.
Buren states:
"The photostated performance sheet is the one
to follow. You will note that it shows a takoap
1)161? over a 50-foot obstacle in calm air at a
52,000 pound gross weight of 1,800 feet, which
compares with the DC-5 rigure at 24,500 pounds
of 1,650 feet. However, if the Budd is flown
at the same gross weight as the DC"3 I am in
formed that it will have a very mudh shorter
takeimoff than it or the J-52.
"Accurate figures on the airplane will be avail-
able in the next few weeks as flight testa are
now under way. I would appreciate your making
these figures available to General Donovan as
they are somewhat at variance with the figures I
g*vo him."
