Double Bogey, The point you are missing is that the entire FIR was closed as a broadbrush reaction with no conclusive research done. It will be re-opened in the same manner.
As a NS pilot you have the comfortable position of a relatively large organisation plus a union to back you up and can take no personal responsibility for risk assessment. Others don't and must make their own assessment. Me included.
If you think this reaction by the authorities was much more than a huge backside covering issue, look at the additional requirements now demanded to begin use of Battersea heliport again. I'm beginning to think they want no trade at all.
