for sure the air war against the nazis stopped Hitler from invading Britain and without using the British isles as a staging area d-day would not have happened as soon as it did. maybe not at all.
Churchill was a rallying point for the people during the "blitz".
the advancement of propeller-driven warplanes reached it's peak in ww2. it's my favorite part of ww2 history. and great naval battles.
my favorite plane of the era is the Supermarine Spitfire. in my opinion one of the most beautiful shapes ever made to fly.
the American p-51 mustang was perhaps the single most capable design to come out of the war.
it used the same Rolls Royce Merlin engine that was in the spitfire but got a greater airspeed because of the design. long-range so it could accompany bombers on long missions.
Another notable aircraft is the DeHavilland Mosquito, a twin-engine fighter bomber made with a plywood frame to save on metals for the war.
some versions were fitted with radar for night interception. the Luftwaffe feared these things.
they also used two of the merlin engines and were very fast for the day.
