"So now following this incident I want the AAIB/CAA to look more closely into helicopter operations over London especially single crew operations
I think this incident shows up a lot of shortcomings in the present situation
The airspace rules are complicated and restrictive in London"
Nonsense. This incident could have happened anywhere and is a situation faced by charter pilots daily all over the world. The UK (especially London) already has probably the most restrictive rules for flying over cities etc (with the possible exception of Canada). It really needs to be put in perspective - I've been flying around London since 1977-ish, and this is the first incident of its type. It's highly unlikely there will be any more.
If anything, it highlights a possible need for more CRM training, not more rules which will only serve to help the industry die even further.
