I used to work in a studio on an industrial estate in Calne, looking out over fields directly up to RAF Lyneham, and there would often be interesting stuff stooging around, C130’s doing Kay San drops, which is pretty spectacular, and other stuff. One afternoon a Puma went past at speed, lower than Lyneham on the hill behind, and close enough to see clearly panel lines and rivets and the pilot, which was impressive, but nothing compared to the Chinook that went past at about the same hight going like the clappers banking round trees and keeping below the height of the surrounding hills like Bremhill. Totally shocking, seeing something that normally chugs around at height like a horse-drawn wagon suddenly behaving like a Ducati motorbike. Saw them in a whole new light.
[edit] just had a look on Viewranger, and Portemarsh Industrial Estate is on the 100m contour, and there’s a trig point on Lyneham base at 156m, so the Chinook was below 183ft, probably about 80-100 as it was avoiding tall trees. Impressive in a thing that size at that speed.
