I always thought that they'd strike an engine at PMQ because of the shocking runway there.
Can confirm that it is significantly better now that it has been redone. The best in the 14 years I've been going there!
I always compared the runway there to the deck of HMS Invincible - (complete with a ski jump to launch Harriers in the Falkland Islands war). We always seemed to hit the ski jump on the runway about 10 knots before V1
Thank God it's gone.
