[QUOTE 3032565, member: 9609"]But do we not have peaceful corners of our green and pleasant land because of our ugly military might.[/QUOTE]
I may misremember, but I have a feeling the last time the peace of the United Kingdom was seriously threatened was in 1940. That's 74 years ago. Low-flying jets weren't much help, because they hadn't been invited yet.
Apparently low flying is particularly useful if the sortie originated from an aircraft carrier. In the Falklands the Harriers used to fly low below radar when returning to the carrier. If they were to fly back high and just drop down at the last minute it would have been easy to work out the location of the carriers as being the point at which all the planes suddenly disappeared off the radar.
If that's your concern, wouldn't it be more useful to train over the sea than the land?
Anyway, this is all getting a bit too challenging for the froth of the caff. If you want a serious discussion, feel free to start one in the right place. For now I'll leave you to your imperial fantasies.
