From further away, what would they look like to an untrained eye?

A small very very fast moving LOUD cloud!

Mr Zorgon: the photos shown for you are good, but I do not talk about it, but clouds passing a plane expelling chemtrails, (or not) are destroyed that way. Take my life as a sailor looking at the sky by bad weather comes and I say they are not normal. It is my opinion are very very strange.

I'm not speak English and use the translator, I hope you can understand I just want to communicate in this forum and I find very interesting.

One question, there is some good online translator ??

Yes but the noise is not recorded in a picture.

I just tried to find some moonlit supersonic-jets to show how they could look like a saucer at night but can hardly find any.

Ones like the shot below could be mistaken as a saucer depending on how the camera is focused and lighting like full Moon.

Again, "flying saucer" is a possible useful cover story for military tests.
