One of the most impressive civil airliners is the Boeing 757. I think it can climb at 7000fpm.
Mr. Toad will know, as he knows all about flying 757s. The 757 really stands on its tail, and is also renowned for its relatively aggressive wake vortices.
Coming home from the west coast minicon trip at the weekend, our 747-400 was achieving a stonking 668mph ground speed! Information was provided by the Sky Map. The wind strength was well over 100mph over the US mainland.
Later on, I took this picture. Any pilots know what the vertical separation would be between us and the aircraft below? I think it's 2000ft for IFR above a certain level, but I'd like to know what that level is.
