Khormaksar March 1964, XP413 sat down in the water on approach into K/Sar
It was very nearly joined by Valiant BK1 XD813.
We were om the approach and we saw these booms and fins sticking out of the water. Just as we approached it we hit a GODALMIGHTY downdraft. I was NH and without waiting to be told I thumped in a handful of Avons because the speed was dropping as fast as the R of D was increasing. We needed it all and we did not take it off for quite a long time.
They are known today as downbursts; quite common in the far east but maybe not thought of at that time.
