For sheer noise, having some ****** at Cottesmore hover directly over me can't be beaten. Him and 2 mates had been coming into land, and the last one hovered backwards for a bit to be directly overhead the group of photographers near the runway end, just outside the fence. Blew umbrellas and things all over the place and couldn't hear a damn thing for about 10 minutes. Not so much a low pass as a low squat-on-top-of-you really.
My father tells a story about a Skyhawk low pass he saw once when he was in the RN. Approached his ship at below deck height and pulled up going over the ship, flashing past just above the main gun and at about eye-level with the bridge windows. Thankfully the two bombs he pickled off took the same trajectory because he left it too late and just made BIG splashes in the sea a few hundred feet away. Unfortunately one his mates had better luck a few days later.
