Below is what I emailed to them. I suggest everyone else does the same or something similiar

Dear Sir,
I would like to complain about the 2012 airspace restrictions that have been proposed.
These restrictions will effectly ground all General Aviation VFR flights for two months and will seriously affect the businesses of flight schools and charter operations (especially Helicopter companies).
I would like to know why these draconian measures are necessary? General Aviation and onshore Helicopter Charter businesses have been suffering from increased regulation/AOC charges, high fuel charges and a recession, this "airspace lockdown" may be the final nail in the coffin for many businesses.
The proposals also state that all pilots will have to flight a flight plan via the NATS website during the entire Olympics period. This online service seems to be plagued with technical problems and will be even worse when more people are trying to use it.
I look forward to hearing your reply on these matters
Regards
