There was a story going around when I was doing the OCU at Coningsby about some daft USMC dare concerning writing your initials on the outside of your F4 windscreen at some stage between take-off and landing....
To do that would mean getting the a/c down below the canopy limiting speed (was it something like 90 kts?), unstrapping, opening the canopy, scribbling your initials, clsoing the canopy again and strapping back in before the a/c departed......
Anyone else hear that?
