Me 163B 'White 11'

I had to look twice, but indeed this shows a Komet, seen from the right rear. At first it looked like the tail was partly sunlit in the dark hangar, until the connection with the runway photograph was made. This was the same aircraft, and it had a unique camouflage! The rear fuselage, the code number '11' and part of the right wing can be seen, but that's about it.
