Good point about replacing Lysanders with Noordyn Norsemen.
OTL After early heavy losses, Lysanders were relegated to secondary roles: search and rescue, target tugs, delivering agents to occupied France, etc. Lysander's only advantage was its 870 hp engine which allowed it to cruise at almost 200 mph. Otherwise, Lysanders were cramped, slow to load, 2,000 useful load (crew + fuel + passengers).
OTOH Simultaneously, Robert Noordyn was developing a bush plane called the Norseman. With only 600 hp, it could carry 3,000 lbs and cruise at 120 mph. Norseman's biggest advantage was its huge cargo door which allowed rapid loading of fuel drums, etc.
Every base, fighter squadron, army regiment, etc. wants a "squadron Hack" to haul a few people, ammo, rations, spare parts, casualties, etc.
During the Korean and Vietnamese Civil Wars, the US Army bought hundreds of DeHavilland of Canada Beavers and Otters. Light STOL airplanes were extremely useful before helicopters grew turbine engines.
Even during Vietnam, the US Army, CIA, Air America, etc. used Fairchild Pilatus Porters, Helio Stallions, etc. to support anti-communist hill tribes.
ATL Everytime I try to do a Lysander wank, it ends up looking like a Norseman with an 800 or 1,000 hp engine. Maybe a Fairchild Husky style canoe hatch under the tail.
