This is coolbert:
Here is an example of independent parallel design and development?
First, the American C-82 Packet. "The C-82 Packet was a twin-engine, twin-boom cargo aircraft used briefly by the United States Army Air Forces following World War II."
And the German Gotha Go 242. "The Gotha Go 242 was a transport glider used by the Luftwaffe during World War II."
"The Go 242 was designed by Albert Kalkert in response to a Reichsluftfahrtministerium (RLM) requirement for a heavy transport glider . . . The requirement was for a glider capable of carrying 20 fully laden troops or the equivalent cargo."
Similar placement of the cockpit, the dual boom, high-wing. Of course the Packet has wheels [the glider had wheels and also lands on a skid running the length of the bottom?], and two engines [note too the windows on the GO 242 are lacking on the Packet]. But the basic design is remarkably similar? Espionage of some sort was involved? Or just logical minds at work arriving at a similar design based upon requirements?
