the first one i cannot recall much at all, but both were poor weather, cross winds and hydroplanning...
i was ops d/o at LHR and i may have been on leave...
the 2nd one involving G-AZLT was the last evening flight in from LHR (my colleague and his ticket desk g/f was on board) and as usual very cross-windy, Oct 1980
pouring with rain, a/c aquaplaned and Capt steered it off the side to prevent an overrun, port gear collapsed,
the port engines gear and wing were seriously damaged,
the skippers name will come to me, a youngish chap i recall
i gather they left the runway and the left wing was badly damaged ? torn off...do not know much at all, not sure what the evac was like, my friend had some skin burns on his arm from the armrest... i am surprised you cannot find an aaib report...i am sure one is around?
it was quite hushed at the time and played down
afaik, the CAA took the loadsheet away from us...
