Hamish and Max Angle... You guys really ought to spend a couple of hours trying to do it. We had a smart-a*se pilot in Heathrow Tower one day who thought he knew all the answers so we gave him a headset and told him to get on with it. Five minutes later he had to give up.
I just wonder if the guys who invented this new machine have ever been near a busy airfield? It would be bad enough at Gatwick or Heathrow but just imagine the carnage at some of the US airfields with 100 tugs running around the taxiways in LVPs, or even good weather for that matter. Will they be fitted with SSR?
