CNN: "Witnesses said they saw an explosion on one side of the plane before the crash, but different accounts placed the explosion on different sides of the aircraft. Ethan Moses said he saw the aircraft burning from its left side, then the aircraft's left engine fell off.
"It tilted to the left slightly and it made a nosedive, straight down," Moses said."
Also from CNN website (re the BA share price dive) the crash ocurred at 9.17 EST. Given the speed with which bad news travels across financial networks and the necessity for fund managers to knee-jerk react to such new, the graph does not seem unreasonable.
The fact that the aircraft had just come out of maintenance could cut two ways. What better time to do something nasty? But I'm sure the FBI will be talking to one or two unfortunate maintenance engineers.
(End speculation)
