Given the mailbag this is generating I feel the need to elucidate a little further - no I don't object to military low flying, no I don't consider aircrew to be dyed-in-the-wool rebellious rulebreakers and I'm sure nobody at Silverstone knew 500ft from 1000ft - I probably wouldn't.
My only position is that if you're going to complain about people's assumptions that you are breaking the rules, perhaps it's best not to write in books about gleefully doing exactly that.
Personally I think if you're going to sit on top of an animal known for startling at at small, inoffensive happenstances (let alone military aircraft) you probably deserve all you get - but that really would be barrow-pushing.
