Witnessed a couple in my times at MPA.
1) Squaddie based on South Georgia needed to get home ASAP. No airfield there of course so resident frigate is dispatched at full speed to collect said individual. When they are within helo range of MPA on the return the individual was airlifted to waiting tristar for UK. Slick !!
2) Girl at MPA had to get back to UK to see dying father. C130 left MPA at around 0300 for Rio. Young lady caught morning flight to UK. Concorde, the rumour goes, was the transport.
