L-129: This design study was done in mid-1941, shortly before America
entered World War II. It was basically a series of long-range bomber
designs, so constructed that they could be easily converted into 
commercial
airiiners. Aithough L-129 was its official TDN, this effort was also 
called
Lockheed "X" with subtitles of Model l, 1A, 2, 3 and C-1 (the only
commercial version). In appearance, all the L- 1 29s were similar to
previous Lockheed transports with only a variation to a single vertical 
tail
in some of the designs. With Tornodo engines the typical bomber 
version, at
a 52,000 pound GTOW, would have had a maximum speed = 363 mph, range = 
3000
miles, landing spoed = 80 mph, takeoff distance = 2295 feet. The Model 
C-1
commercial version was to carry up to 36 passengers about 1380 miles 
with
similar performance numbers at a slightly less GTOW of 44,000 pounds. 
No
L-129 of any tupe was to reach production.
