Whilst I admire Mr Branson's response and having done the PCMIO course it is as you say refreshing to see the speed at which the facts are emerging. However, I do think the emphasis is entirely different i.e. Virgin Trains V MOD.
The cynic in me would imagine that there is more of a requirement for a company such as Virgin to get the facts out quickly. Their well being is dependent upon public support to a greater degree than the MOD.
I am still convinced that the MOD also do an excellent job within the PCMIO duties.
