How about opening all the bits of the UKLFS that we don't normally use (eg Kent, Middlesex, Surrey & Sussex), down to 100' AGL, for a bit of serious OLF practice? Throw in a full airborne BG assault on Parliament Sq with backup from the Household Cavalry in full war role ...
Oh, forgot, there's a law against demonstrations within a mile of Parliament. Wonder if Aunty Betty would give us dispensation for the afternoon?
