We, as mlitary aircrew dont need to give you a reason as to why we need to low fly WorkingHard. Who are you to deserve a special brief on why we need to do it? Just keep paying your taxes and rather than question the means by which we provide your security, I would rather you just said thank you and went on your way. If you want to know the 'official' justification for low flying, go to the RAF website or trawl through the MOD sources, this is after all a RUMOUR forum and therefore needs to be taken lightly.
I know that this is going to inflame your cleary narrow minded and polarised little brain, but quite frankly, I dont give a monkey's. Now kindly poke off and annoy someone else.
I dont expect a reply, although will undoubtedly receive one as you dont seem to be able to keep out of things which dont affect or concern you. Now why dont you go to the "company pilot" forum and let us worry about all things military.
Yours
DS
