When I had the Green Satin bench at Akrotiri, 1962-4, 13 sqdn were on some exercise where the crew got dressed up in funny suits.
They started sending GS Tx/Rx's in to me claiming that they 'unlocked at height'.
These all tested out OK and after a couple of days my presence was requested on the line to speak to the crews.
When I pointed out that the operational spec of the kit was up to 60,000 feet, they said 'Oh!' and stopped snagging the GS.
