True, WHBM, and also i think wardair was registered with a charter broker pool like many airlines who had spare downtime for possible upcoming ad-hoc jobs - chances are this was planned as the BCAL CFU RTO incident was in July and my flights were in mid Aug of 1972.
G-AWYS Corfu 2
our outbound LGW-DBV 2 weeks before was a Northeast trident so its obvious this DBV rotation was subbed out weekly for much of the high season
was not a Yugotours flight but a Horizon Holidays flight
the WD 727 was a LGW regular from 1966-1973 when she was sold abroad to Sth America
she was a beauty - glad you enjoyed her too
