Sometimes the unthinkable does need to be thought. But after an exhaustive investigation by the AAIB (during which they will have considered the unthinkable, the thinkable and everything in between) they have come up with a number of facts and conclusions, none of which include the scenario you suggest.
To make this suggestion, in disregard of the investigation findings and with no evidence whatsoever to support your accusation (and much to disprove it) is scurrilous, ignorant and dishonourable.
