Can I just point out that it was MD600 Driver in
post 17 that first speculated a cause to this incident. All posts prior to that were identifying the type.
It was then general discussion for another 30 posts before KJ speculated about an engine problem; then another 26 before other speculations/observations are made by nigelh and md600 driver, both of whom I am led to believe are friends of Nigel F.
Thank you.
