During Granby we had a Herc arrive back at Lye with a few feet of (starboard I think) wing missing. Apparently a contre temps with a hover taxying Super Puma in Saudi was the cause! I undertand that the Herc was starting up when the rotor caught the wing, punctured the underwing fuel tank which covered the unfortunate Air Eng or Loadie with fuel! Fortunately no fire! A bit of cardboard and tape over the end of the remaining wing got it back to blighty for repair.
