The thing I remember most about the MH-53 is being woken up an hour early or waiting for an hour when on TSW duty refueller at RAF Stafford because of a ZULU/Local ETA mix-up by either someone at the Mildenhall end (not so likely) or someone in the TSW ops room (very likely).
I've got a 21st SOS bar coin thingy (that I was given at silly o'clock in the morning whilst on duty refueller some time ago) stashed away somewhere for all those "who's round is it anyway" occasions when working with our colonial brethren.
A good bunch of lads, it'll be a shame not to see the Super Jolly thundering through the skies anymore.
