strange circles in the sky
On Tuesday, I was in my car with my girlfriend, and she said, "Why's that plane doing that?" I looked in the sky and could see a plane and it's vapour trail doing a circle in the sky. I said that the pilot's were probably lost and were just having a look around. She knew I was joking.
Five minutes later, another aircraft did the same thing. I was stuck in some temporary traffic lights, so I saw it do a turning circle and then continue on it's merry way. Then so did another.
Due to the vapour trails, they must have been in high altitude alirways?
I was to the north of Leeds at the time, at about 10am. The plane's could've been anywhere in the Northern region I suppose. So what was happening? Was it spacing becasue of a particulary busy time. That's what I told my better half.
Cheers, just curious
