I
remember the Gnats at Cosford when I was there as an instructor. We used to taxi them around so that the studes could get some marshalling practise in. Not the biggest of cockpits as I remember and it had that 'door bell' chime warning sound which always sounded very dainty to me. Should have been a great klaxon sound blaring away. The anoraks kicked up a fuss when we painted out the names of the pilots on the side and put the instructors' names up for a lark...
ah yes, bats in hand, Instructors/wannabee pilots following your EVERY instruction, up to the point where it was dangerous to continue, which usually meant a few "father like" words from the Instructor stood beside you! Also sitting in the back of the Gnat doing engine runs, whilst your oppo was "controlling" it from outside...happy days!
