Sorry to butt in but could you give this a go?
Any RAF aircraft, current or past that could get airborne off Manchester Rwy 23 and get to FL 410 by overhead Birmingham airport? The parameters are: A full pay / bomb load, 1/4 fuel and fixed wing. Gliders (the 410 bit should screw this anyway, ditto helicopters!) and missiles are excluded. The flight path is ahead to 5 miles then direct which should rule out those planning via Land's End (assuming the fuel didn't give out)!
As an exercise, any military aircraft, F16 etc but with the same parameters?
There is at least one civi aircraft that can!
