GM,
Pprune is a very welcoming and tolerant site, so I am prepared to give you a little more slack than your post may deserve:
Imagine you are sitting by a fast stretch of straight road, one with a nasty z bend at the end of it. It is misty - there may even be patches of fog. A car comes down that road at 80mph. A little while later it is found upside down in a ditch by the Z bend. What happened? It COULD have suffered brake failure or steering failure or a blow out or there could have been a deer or sheep on the road but by far the most likely cause is that the car was going too fast in inappropriate conditions and simply went off. That is a reasonable analogy of the Chinook crash.
Well NO. Try:
Imagine you are sitting by a fast stretch of straight road, one with a nasty z bend at the end of it. It is misty - there may even be patches of fog,
but the only eye witness says that the bend was visible. A car comes down that road at
a speed appropriate to the conditions. A little while later it is found upside down in a ditch by the Z bend,
with the brakes and steering disconnected and the engine management system burnt out. It subsequently turns out that driving instructors are refusing to drive this type of vehicle and that the owners are suing the manufacturers of the engine management system because it is not fit for purpose.
Spot the difference?
