Tunnel Phenomena in Clouds, Multiple Sightings (my own included) With Video/Photos, Please Explain

I was walking to the store tonight and noticed a strange streak across the cloudy sky. It looked like some sort of tube or something, and was like nothing I have ever seen.

A few hours later I stumbled upon a coast to coast sighting of someone claiming to have seen a similar phenomena. Both my event and the CTC event took place in Washington.

But with further research I discovered this! Another spiral in Canada, except this time it was in Prince Edward Island, which is on the other side of the continent.

Any ideas?

Thanks,
Nyorai

Thats called a hole punch cloud. I think they are formed when aircraft pass through mid level super cooled clouds. The wispy bits are called cirrus clouds, which are at a higher level than the lower clouds where the hole is. The phenomenen is more cmmon than you think. Check out the link

Cool link and nice pics. I'm always looking up, watching the weather, but have never seen this before. Fascinating!

I can understand why someone would be intrigued by seeing this.

Look at the dates on those pictures to that link. Wouldnt H.A.A.R.P cause simular disturbances?
