[Dan O'Connell]

Franek is right, it was simply a six digit number in order to enter the unknowns. I picked 9xxxxx as there were never any assigned to Me 262's.
Messerschmitt Me 262: The Production Log 1941-1945 is substantialy larger than that data base.
It suffered an extensive crash at Stormbirds and it appears doubtful that it will ever be repaired.
Very best, Dan
