What was the best bomber plane of all time?

B52 Stratofortress. During the Vietnam War one B52 could carry up to 108 750lb bombs. That was equal to 10 WWII bombers.

I believe the Avro Lancaster was the best bomber of all time. It was essential to winning WW2. Lancasters took thousands of boys to war and brought many men back. It made the difference between winning and losing. -If the Allies had lost there would never have been a real peace.
