Every time we get a thread relating to an accident on this forum we end up with the same old procedure; someone posts with a speculative comment (some are well-informed - some aren't) and then someone else feels obliged to defend the honour of the people involved, then we end up with playground bickering.
Eventually we all come to the same conclusion - that accidents leading to the loss of life are very sad and that no matter what we think, the AAIB will investigate thoroughly and come up with a report from which we can at least draw informed conclusions.
This is after all an open forum which is as close to a virtual crewroom as we are going to get - why shouldn't people speculate on the cause of an accident? Weather, pilot error or mechanical failure (or combinations of these) are the big 3 killers - why not discuss them in an adult fashion so that we may all learn from the mistakes or misfortunes of others.
Just because one person thinks a pilot may have made an error doesn't make it so and doesn't mean that others have to take offence by proxy.
