No..I think what you are thinking of is the Me-163...it was the little rocket plane that would zoom up over the bomber formations then glide down while shooting at the bombers.

The main issue with the 262 was that the BMW-004 engines were only good for 10 hours of flight before having to be overhauled. The metals were just not up to the RPMs that they were creating and lots of cracking would be created in the turbines.
