CNN are reporting eyewitnesses saying the plane was flying at about 10,000 feet and flames were coming from the tail section and suggesting an electrical fault. 🙁

All speculation at this point, but in the absence of a statement from the MoD it’s only human nature to wonder out loud.
Trouble is that until some sort of authoritative statement along the lines of ‘preliminary inquiries suggest that …’ is released, the conspiracy theorists will have a field day.
