In 1952 I was stationed at Barksdale AFB in Shreveport LA. about 6:00 a.m. this cigar shaped UFO, about 300' long, approached about 800' to a 1000' in the air, it had port holes every 10' or so.
It came in toward me, turned sideways, remained motionless for about 2 minuets or so, then turned around and sped off in the direction it came from.
I went to the expermental hanger at Barksdale, and asked the guard if I could have a look inside.
He said: NO.
Then I told him what I saw, he said he had seen the same thing, at which time he opened the man door and said: Have a look, we have some goofey looking stuff, but nothing like that.
