We were returning from a mission to Berlin.
The object pulled up alongside of our B-17 and appeared to just observe us.
One of our gunners ran a string of 50 caliber bullets down the length of the object. but we didn't see any effect on the craft.
Therupon the object left our vicinity, rapidly.
We had departed England for the run at about 8:00 a.m..
Many other crews sighted these objects during WWII
