Real world Berlin to Brazil proposal, FW 200L
There is a real world build that could be used to cause consternation, the FW 200 B/D.
The Finns and Japanese each ordered a pair of B model airliners, for obvious reasons
these were not delivered and were taken into Lufthansa/Luftwaffe service under the
D designation. For a short period at least two were operated in full Lufthansa livery.
Now where the cat gets amongst the pigeons is that while fuselage wise they look
just like the A model airliners, they have the wing, engines and landing gear of the
military C models.
So combine an A fuselage with C wings etc., paint it in Lufthansa silbergrau and black,
add the civil codes and take it to a contest and watch as someone tries to move it
into Flights of Fancy/Hypotheticals.
