I do recall the Red arrows on route to the Southport airshow passing over the Old Trafford football ground at 1000' then over Warrington (I was in a C150 in the LLR south of Warrington at the time, excellent view)
The thought did occur: - A Hawk is still a single engine A/C, Ok so I know the reliability of a turbine engine is greatly superior to a piston, and military pilots are exceptionally well trained. But where is the aircraft going end up when the N1 rapidly reduces along with the EGT. There are not all that many open spaces in that area.
