How about this..... C-17 1000' above going the opposite direction. Unfortunately didn't have the camera ready and only got one shot as he was about to pass overhead. Image Unavailable, Please Login
looked up vapour trails on youtube, check this vid of a fighter plane http://www.youtube.com/watch?v=koAQN3n4pcw about 20-30 seconds in is an awesome speed of sound cone effect, the rest of the vid's ok, but the cone is must-see.
As long as two planes do not make contact or fly into an air disturbance that messes with the engines, it's fine. THIS is a bad day http://www.youtube.com/watch?v=LPz9ZNFuhng crowded skies? go outside and look up - Burt Rutan
When you are the slowest thing around you get passed by a lot of the big boys going higher and faster...... This DC-10 passed almost directly over 2000' higher. The IL-76 was a bit higher and separated..... Image Unavailable, Please Login Image Unavailable, Please Login
Good thing he could eject. Anyone remember the Cessna 172 / Boeing 727 collision in the US back in the 70's?
