COIN aircraft.
Are we going to use Pound coins or Euros to operate them? Will they have a nice red 'gun' button and make exciting machine gun noises?
With a different game cartridge, they could be used to depth charge submarines etc.
Cor, that would be fun and would be very cheap too! We could of course keep all the Air Staff and let them pretend until they retire on full pay.
Only a small overhead to keep the 'train on the tracks'.
