Change of thread
The "monitored approach" aspects of this thread have little to do with the original topic. If people want to continue it I'd be happy to copy the relevant comments to a new one in the "Tech Log" forum which would be more appropriate than "Rumours and News" and leave this one for the actual subject of the NTSB report in question. But only if there are a few indications of agreement that it would meet with approval.
