In the latter years of the Bev's life the UK - Cyprus trip became 5 days as we obviously needed a day off to recuperate once we got to Cyprus. Also we frequently routed Luqa - Benina/El Adem - Akrotiri/Nicosia.
We did once get a Bev out to Akrotiri in about 18 hours. Mid afternoon at Abingdon, sudden panic, Crew A and B given 1 hour to go home and get their kit. Crew C did the flight planning for Abingdon to Luqa. Crew A came back, got airborne for Luqa. Crew B got into an Andover and were flown to Lyneham where a Comet was waiting to fly them to Luqa, overtaking the Bev (OBVIOUSLY). Crew B did their flight planning in the back of the Comet and got some sleep. Crew A arrives Luqa, aircraft refueled, Crew A get in the back and go to sleep while crew B fly the aircraft to Akrotiri. 18 hours from the shout and one aircraft and one crew rested and ready to go in Akrotiri. Shows what could happen when the chips were down.
Mind you, a couple of weeks later on the return to UK we lost 2 engines with a load of indulgence pax onboard and spent 5 days in Paris.
