It has been about 10 years since I last used Gatwick. When I last did there was a Comet with clipped wings near the terminal. Further along when taxiing out, near a fire training hull, I could just see a tail which looked to me like a Gloster Meteor or Westland Whirlwind, no idea if they are still there but guess not. Even at UK's busy airports there is usually something unusual to see.
