Because ME262's got shot down loitering around airports all the time. Jets were vulnerable creatures.

The VRDK was a motorjet, a rudimentary type of jet engine where an external power source drove the engine's compressor...................

The jet was intended solely for high-speed dashes, with only enough fuel for about 10 minutes of use.
