i was duty traffic officer at LHR in ops for BMA 1977-1985
i cannot help you re VC8 ops 1972 although i lived near SEN and channel airways was my local airline but i dont know what happened to them at BOH re BMA picking up their flights...
re BMA DC9's -15's
when i joined we were just getting the the leased Finnair a/c still with its finnish regn op'g LPL-LHR OY-LYB
and our own N reg a/c then became G-BFIH/G-BMAA a/c op'g LHR-MME
we had about 9 viscounts operating LHR-LBA IOM MME EMA BHX LPL
Friday nights was all viscounts at LHR as the DC-9's went off to op the Jerseys because at weekends in the summer the DC-9's op'd out of EMA and LTN and almost everywhere else we went from to Jersey !
(along with alot of the viscounts too, so Jersey was a major player)
with the DC-9 we also did MME-PMI on friday nights and RMI too, sometimes we did LPL-Tarbes, LPL-ALC,PMI,GRO and some other charter places too.
we did LHR-PMI occasionally with the DC9.(charter)
we also with the viscount did LPL-PMI, BHX-MAH in the summer on night charter flights. a 5 hour trundle through the night lol
6 x DC9 -15's were op'g during my time eventually,
G-BMAA/B/C G/H/I
85 then 90 pax seats
2 x DC 9-32 came in too before i left
G-BMAK/M
105 seats i think
i think thats all i can remember,
sometimes when british rail went on strike we used the 707's as well on domestic flights.
and they dropped into LHR on fog diversions on early mornings if EMA,MAN or BHX was closed...all holiday charters.
all sun tanned punters and the cabin smelled of ambre solaire !
GLA/EDI and BFS came later on whilst i was there.
all DC9 services.
although the viscount went to BFS sometimes.
