As WHBM mentions KT (Beatours) started up for summer 1970 with the Comet 4B's and their flights were known and called in the terminal as 'Tango' but dunno why lol
BUA, Laker, Dan Air, Caledonian, and Court Line were all furious that the state owned airline were setting up as the competition in their perilous IT markets.
Enterprise Holidays, Flair, Hickie Borman, and Martin Rooks Holidays were all owned by BEA group thus KT flew for all of them, plus also for Thomas Cook Holidays too.
Silver Wing was also a BEA company, more upmarket and had used BEA scheduled flights mostly until KT was established.
The Comet had shown it had the longer range and could fly the longer holiday routes to Greece, Romania, Bulgaria, and the Canary Islands.
Clarksons had first used Dan Air Comets for these routes in lieu of Court Line 1-11's.
(Previously British United and Caledonian Bristol Britannia's were used for such longer flights)
In 1971 the Enterprise summer brochure was emblazoned with a double page spread on the 'new' Boeing 707's that KT would use to fly for their holidaymakers - at the same time Monarch had bought Boeing 720B's to replace Britannia's for Cosmos Holidays, ''Look what we have bought for you!'' was their summer 1971 brochure tagline.
Dan Air, BMA and Lloyd International had all bought a pair of old 707-321's to join in the big jet charters.
Donaldson would soon follow to buy 4 of the ex Pan Am guzzlers.
KT had wanted to buy some AA 707-123B's but HM Govt blocked this purchase and KT were forced to take the ex BOAC 707-436's.
KT did lease in 707's from Geminair (Possibly via Templewood) and also from Dan Air.
Channel Airways were also looking at buying ex Continental Airways Boeing 707's.
Dan Air had been flying Comets on IT's since 1966 and were adding many examples to it's fleet sought from BOAC, East Africa, the Middle East, South America and Malaysia.
Channel Airways ceased operations at the end of 1971 having bought 5 ex BEA and Olympic Airways Comets in 1970 for the large Lyons Tours IT contract.
4 examples then went to Dan's in 1972. 1 of the 5, G-ARDI was DBR and was used for spares only and was WFU at SEN.
This was the only Comet ever to fly into SEN.
The last KT Comet 4b flight was 31 OCT 1973.
