The 'pins left in ' scenario should not happen with most RAF Hawks - as most RAF Hawks have the modified pin stowage on the port glare shield,thereby giving the grouncrew an excellent view of pin location.
The original pin stowage on the left canopy longeron was not as safe because if the pilot forgot his pins - it would not really be obvious to the groundcrew !
Ironically the Reds have the canopy stowage because the 'smoke on' indicator lights are up on the glare shields.
There is one other UK based hawk with the canopy pin stowage in the rear cockpit because of lack of space on the glare shield.
