When completed, it was capable of carrying 750 fully-equipped troops
I wonder if that should be altered to "...it was capable of carrying 750 very scared fully-equipped troops".
The idea was to ferry those troops, or equipment, by air (to escape the U-Boats) across the Atlantic to reach the combat zone.
I have a wartime Popular Science article which apart from enthusiastically describing the enormous dimensions of the "soon to fly" behemoth mentions an estimated cruising speed of
145 mph. That's not much faster than the Gigant?
So, I have this mental picture of an enormous aircraft lumbering along close to the water heavily loaded with many many poor souls heading off to war without any defensive armament. Sounds bad.
