My all-time favorite:The spitfire.
This particular airplane (Mk IX) was built in 1944 and is said to be the first allied aircraft to have landed in France after the D-day landings.It was later sold to the Dutch airforce and after that to the Belgian Air Force.Greetz,Brummbar

The initial development of the Mustang was completed very quickly,in just 102 days.However ,the plane that came out of the hangar at that time had no engine or gun mounts.The first production P-51A didn't reach Britain until about 18 months after development began.Duxford Airshow,Flying Legends.Greetz,Brummbar
