Have done extensive research on the Lightning, in terms of sinking back onto the runway after take off I make it five as follows
1) 6/5/66, XM213 of 226 OCU, S/L Paul Hobley
2) 27/9/66, XR714 of 111 Sqn, F/O Graham Pritchard
3) 9/1/68, XN728 of 92 Sqn, F/L David Cousins
4) 29/10/71, XR711 of 111 Sqn, F/L Eric Steenson
5) 7/8/72, XP700 of 29 Sqn, F/O George Fenton
The first four ended in the barrier and F/O Fenton ejected after take off. If anyone knows of any others I would like to hear about them.
There were certainly two incidents where Lightnings were landed wheels up.
