And surely the Arrow Air DC-8 cargo flights previously seen at Manchester were ad hoc charters rather than a full scheduled cargo service.
I could well be wrong, but I'm not aware of Arrow Air ever previously operating fully fledged cargo flights into the UK, especially on a scheduled basis.
But again, I stand to be corrected.
Of course, passenger flights by Arrow Air DC-8 and DC-10 were regularly seen in the UK and, in particular, at LGW, where the airline flew scheduled flights from Denver and Tampa during the mid 80s.
There must have been loads of ad-hoc cargo flights into Manchester over the years, but I think the topic is regarding fully fledged scheduled cargo flights rather than including ad-hoc cargo movements.
