I lack the expertise to have an informed opinion on the technical arguements but the injustice is clear and I fully support the campaign to clear the pilot's names. My post is just to say "stick at it" and take heart from the apparent success of the Hercules retardent foam campaign that appears to have borne fruit. Whilst it is immpossible to say with certainty that the thread on pprune was a prime mover or even that it contributed to that cause, it is probable that it did and can not have harmed it in any event.
I know for a fact that this forum is viewed by the top brass and to remove the thread would only diminish the campaign and give succour to those who would prefer it to go quietly into the night.
Good luck and keep going.
