Cannot place that one Spring Heeled...
I do recall when standing outside on the Ramp on the LHR November stands at T1 (opposite runway 28R) early one Spring evening in the 1980's when an SAA 747 Super B touched down and a huge ball of flame came out of the front from #2 (I assume a Surge upon selecting Thrust Reverse).
All very dramatic, and the AFS soon came out and escorted the Jumbo to a Stand.
It was also odd for an Evening arrival, as the SAA Jumbo's always came in to LHR from JNB and CPT in the early morning.
(BTW we had a Traffic Officer colleague at BMA LHR whom we nicknamed Springheel Jack)
