We have built a total of about 1250 of this aircraft, but only fifty were allowed to be used as fighters - as interceptors. And out of this fifty, there were never more than 25 operational. So we had only a very, very few.

We had at our disposal the first operational jet, which superseded by at least 150 knots the fastest American and English fighters. This was a unique situation.

We were trying to defend ourselves because our mission did not consist in fighting in the air. We were fighting against the ground only.

This technology was just beginning. And, in addition, Germany was very poor on war materials, especially on chrome-nickel and other steel, which were needed for the blades.

When I was fired from my post as General of the Fighter Arm, I was to give proof that this jet was a superior fighter. And that's when we did it. I think we did it.

The whole concept was bad. But in this desperate situation, when somebody had a revolutionary idea, then he could really send it through.

This would only come if you have a revolutionary change in technology like the jet brought about.

The total period averaged between engine changes was unbelievable - 12 hours! And since Hitler had given the order to use this aircraft only as a bomber, there was another mistake made: to build an even smaller aircraft with only one engine in top of the fuselage, behind the pilot.

The throttles could only move very, very slowly, always watching the temperature, always watching. And even in throttling back, you could bust it, even being very careful.
