Having had a think overnight how easily one might disable the plod chopper, here's a low risk approach. Naturally, one has no desire to get shot/injured/do porridge, so its slightly more high tech than would be required.
1. Fake a temporary 'unescorted' pass
2. Drive crash vehicle onto camp & park it up in one of the 'long term car parks'
3. Return to camp with 'getaway' vehicle (could be a bicycle)
4. Wait until its dark
5. Move crash vehicle to within sight of target
6. Position oneself in sight of target
7. Using previously installed remote control (easy with electric power steering and automatic transmission - they do it on Top/Fifth Gear all the time) drive crash vehicle as fast as possible into cockpit of helicopter.
8. Make escape in a slow, orderly fashion on bicycle in resulting confusion.
No heroics needed ramming barriers getting into the camp, no getting shot at, no raising the alarm before the crash vehicle is on final run in, so hopefully no porridge!
How long before we see Police helicopters parked in revetments, or even hardened aircraft shelters?
