Terrifying final moments of doomed Russian jet: Flight data reveals plane lurched up and down then passengers were sucked out in their seats - as US satellite detects heat flash suggesting a bomb

From the Daily Mail:

Doomed Russian holiday jet lurched up and down before plunging 31,000ft after being blown apart, bosses claimTravellers still strapped in seats sucked from stricken Airbus A321 through hole at back of jet when the tail blew offPlane crashed into Sinai peninsula killing all 224 passengers and crew just 23 minutes after leaving Sharm El SheikhPM said security officials are ‘looking very carefully’ at whether there is a safety risk to Britons travelling to EgyptHe refused to say what type of impact could have caused the crash but said the St Petersburg-bound Airbus was reliable and would not fall into a spin even if the pilots made a grave error because its automatic systems would correct crew mistakes.The captain did not make a mayday call or contact traffic controllers before the crash, airline bosses added, contradicting earlier claims by an Egyptian official that the pilot radioed complaining saying he wanted to land at the nearest airport because of technical problems.British military analyst Paul Beaver said he thought the crash was most likely to have been caused by a bomb
The data does not show the heat flash travelling at any time, as would be the case had a ground-to-air missile been launched in the plane's direction.Instead, the satellite evidence illustrates that there was just a single burst of ferocious heat on the jet's path.
That has now opened up the possibility that a bomb on board,That has now opened up the possibility that a bomb on board, or an explosion in a fuel tank or engine as the result of a mechanical failure, caused the plane to come down.
