A bit of thread drift, but when I was at Marham, the Lightning OCU came to us for several months while Coltishall was having its runway resurfaced. Each squadron had a list of blokes who wanted a ride in a T4 should the opportunity arise. The theory was the flight would go to the the bloke on the top of the list.
One day I was in the crew room when the phone rang. "Anyone available for a flight in a T4?" I considered finding the list for about 2 seconds, then said "I'm on my way"! Brilliant 40 minute flight - the bit I remember most was 0-35,000' in around 4 minutes - about 14 minutes quicker than a Victor K1!
