3eng,
Bearing in mind that the VC10 is still one of the noisiest feckin things on the planet, I was first posted to BZN in 75 and it was obscenely noisy then, you have to take RA's comments in context.
How come it's only once the Herc arrives that the noise complaints start, it does rather infer it was all peace and quiet with **** all going on up till then.
