With regards to prosecution for 'Corporate Manslaughter', Tinytim is correct that the law was tightened but my cynicism is based on reading of a prosecution last year brought under the new law (if only I could remember the details!) where the case was dropped before it reached court. Howls from the families involved but 'not enough evidence' and all that. The Brits have a very bad record in prosecuting corporate manslaughter.
As Pinkman says - no one is learning the lessons from other airfields. Do you think that the other regional fields of the UK all thought, "Wow! Let's read up our regulations and make sure we know what to do." ?? Do you think the CAA has decided, "The next time a field announces a resurfacing project, we'll be sure to make sure that they have learnt from others. After all, our job is safety." ??
No. Me neither.
