I totally disagree with those who suggest that the AAIB is being disingenuous in the initial or revised reports.
We are being kept informed by very early progress reports and have some way to go in the diagnosis of the cause of the accident.
Will we ever know the true cause? Well, if it was due to a cellphone jamming transmitter, then you youngsters should put a note in your diary for 2038 when the government confidential files for 2008 MAY be released.
