 * Passenger manifest - Russian Emergencies Ministry (214 Russian, 3 Ukrainian)
 * It was initially reported that pilot reported some problems with radio transmission, asked to land at the nearest airport. Subsequently, Egypt denied that emergency landing was requested, saying that normal radio contact was maintained until plane disappeared from radars (TASS quoting Egypt civilian aviation minister Husam Khamal).
 * Early media reports claim that some engine problems were reported earlier in the week.

Observations

 * The burnt wing is upside down. (May be from 2014 in Algeria?)
 * The nose section is intact. Cockpit roof is crushed, cockpit came down upside down.
 * The tail section came down intact in upright position.
 * Flight data (above) suggests that pilot struggled to ascend (not clear exactly why), but the plane stalled and went down into a spin. That could eventually rip off the tail section. But an explosion on board is not excluded as well. So far, some contradictory and confusing information. An investigation will be conducted, and Airbus representatives went to the scene. Wreckage and black boxes are recovered. So we will know, in the end.
 * An investigation area is currently 16 square kilometers, suggesting that the plane broke up before hitting the ground.

Past tail strike
This official incident description is said to involve the same plane. Indeed, past registration record confirms that this is the same plane.

Heat flash
"Satellite detected heat flash at time Russian jetliner went down", CBS, 2.11.2015. "CBS News' national security correspondent David Martin reports a U.S. infrared satellite detected a heat flash over the Sinai at the time the Russian plane went down. The data is still being analyzed in an effort to determine what caused the flash. One possibility is a bomb, but an explosion in a fuel tank or engine as the result of a mechanical failure is also possible."
