Next up, Mr. Garibaldi posts about a DARPA project for a hybrid ground effect/seaplane heavy lifter that could deliver cargo all the way across the Pacific ocean in a day. It is also twin fuselage.
Lastly, via a Wikiwander I wan across a twin fuselage variant of the Messerschmitt BF-109. The Z or "Zwilling" version was an interceptor which would have been armed with five 30mm cannon which would have been a bad day for the Eighth Air Force. Only one seems to have been built and it was destroyed in an air raid before it could fly.
Pretty strange to find all of this all at the same time.
