After five years operating LBA-LHR, BMA brought the DC9 in to replace the Viscount, although the latter still operated several weekend flights. I know the Series 14/15 didn't have leading edge flaps but I thought they would have been able to cope with the shorter LBA runway prior to the extension. Maybe not. The DC9 didn't last long at LBA anyway; by November 1985 the 1-11 G-WLAD was on the route and stayed until April 1987.
The BMA LBA-JER flights were a comparatively late entry for the company, starting in 1993 after Dan Air disappeared. As per EMA, BHX, LTN etc., several rotations at the weekend and largely on jets by then.
In 1996, a pair of ATPs operated the BM flights between LBA and GLA. Both aircraft were, in fact, operated by Manx who had been the previous operator on the route, but they wore the full BM Diamond livery. I believe the transfer of the route from Manx to BM may have had something to do with Sir Bishop, then in charge of Airlines of Britain.
They were interesting times.
