I seem to recall 60K as the limit on VHL AI.
One day, at a much lower level after an engine air test, I went sight-seeing around the west of Scotland, and en route back to Leuchars very low in Glen Tay, with the bit between the teeth, a sudden very loud bang caught both of our attentions. No lights illuminated, and no handling difficulties were apparent, although on a slow speed check, it all seemed quite lively.
Taxiing in, the sailors were all pointing at the aircraft in curiosity and amusement which was explained when I climbed out. A large amount of metal in the form of tanks, pylons and dummy missiles was gorn. 6 o'clock 200 yards on the Tyndrum Hotel. Made the TV news etc. One of the looms had frayed firing all the ERU's.
Twice had runaway gun at Deci which caused concern, but no injuries.
Quels jours heureuses.
