Vapour trails from military aicraft

I thought I would put this post in the ufo section. I had one on vapour trails on Tuesday in the ‘off topic’ section.

This morning the vapour trails returned and while they can be explained, they seemed mysterious to me as I
watched them being created. What really surprised me was how quick they appeared which would probably
indicate a military aircraft travelling at high speed.
Yesterday and Wednesday the sky was clear all day and I didn’t notice anything, but today, Friday, the sky had
the same wispy type of clouds that I saw on Tuesday. This would indicate particular atmospheric conditions for
these lines and circles to be visible to the naked eye.

The clouds lately have been a bit weird. Maybe it’s a late Autumn thing.

The lines in the sky on Tuesday were dead straight like they were drawn with a ruler. Today they were curved
and circular. This all happened between 10.25 and 10.50 am Friday the 6 th. of May.

I don’t know why I happened to look up in the sky but I was surprised to see this huge S shaped trail appearing
before my eyes.
It appeared within 10-20 seconds descending in a hard right-hand turn, went straight for a while, then did a
hard left-hand turn. Through my binoculars you could see a tiny speck of an aircraft at the start of the vapour trail.
As I said, they probably were military aircraft doing training but the speed was astonishing. The G forces for the
pilots must be tremendous.........what do others think ?

Its white water birds or possibly an illiterate skywriter.

Pretty interesting but not that mysterious.

No sonic boom and reasonably tight bank so not maximum speed for a military jet aircraft.
Pilots with G-suits can handle up to 8 or 9 g's (positive) in sustained turns these days. The suit constricts blood flow to the legs so they don't black out as it runs away from the head.
I think we sometimes get surprised by apparent speed of things but appearances can be deceiving.

Single engined training aircraft perhaps but no real mystery. Just a pretty picture in the sky. :D
