In such circumstances, the pilot might attempt to steer by enginethrust imbalance or flap control, which may cause or need speed alterations that could effect stalling. And such could be repeated – until all height be lost. In other words, it may be possible to regain control; but the effort of striking the required balance, in the dark, could cost the plane its entire elevation
Can we conclude anything from the fact that the plane swerved first to the left, and then a full 360 to the right?
"An EgyptAir flight lost early Thursday over the eastern Mediterranean with 66 people on board fell 22,000 feet and swerved sharply in Egyptian airspace before it disappeared from radar screens, Greece's defence minister said.
"The plane carried out a 90-degree turn to the left and a 360-degree turn to the right, falling from 37,000 to 15,000 feet and the signal was lost at around 10,000 feet," Defence Minister Panos Kammenos told a news conference."
Another, though unlikelier, possibility is that it was destroyed by the forces of a mischievous or misinformed nation. After all, no terrorist organisation has said that it is responsible for it
The pilots never made a mayday call. If the stab detached, the co-pilot would have immediately made the mayday call as the pilot tried to regain control of the aircraft. There was enough time for them to do so. When that Alaska airlines MD-80 went down, even though the aircraft was violently changing altitude, the co-pilot was able to make a mayday call.
IF the voice recorder is recovered all questions will be answered.
However, I would like to add that just because the transponder is reporting a turn, it doesn't mean the entire plane is with the transponder. If the aircraft broke up due to a bomb, the transponder could have been separated from the rest of the aircraft.
I remember early speculation that the Rio to Paris Air France flight that crashed into the Atlantic was terrorism, until it turned out it wasn't.
And then there was MH370 and the speculation that, maybe, it was aliens...
In this case it might have been terrorism. But it might well have been something else, such as a structural failure. After all, mechanical failures and pilot error still cause more airline crashes than terrorism. And it's not like Egyptian airlines have such a sterling safety record that it's inconceivable that their planes could crash absent someone trying to make one crash.
Of course, some people are so emotionally vested in it being terrorism that they'll just insist it was regardless of the fact that at present we have no idea what caused the crash. And if we find out that it wasn't terrorism, most such people will declare that they were right to assume it was terrorism.

Maybe, maybe not. Sometimes the CVRs don't shed much or any light on an incident.
The FDR (flight data recorder) is usually of more use in these investigations.
Now they're reporting that they received automated alerts from the plane shortly before it crashed. Here's an article from NBC News, which has this info on it:
Quote:
The report includes the plane-to-ground messages sent in the final minutes of the flight:
00:26Z 2600 SMOKE LAVATORY SMOKE
00:27Z 2600 AVIONICS SMOKE
00:28Z 561100 R FIXED WINDOW SENSOR
00:29Z 2200 AUTO FLT FCU 2 FAULT
00:29Z 2700 F/CTL SEC 3 FAULT
The information would suggest the possibility of smoke or a fire in close proximity to the electronics and equipment bay of the Airbus below the floor of the cockpit.
An "FCU" refers to a unit in cockpit the pilot uses to input instructions into the flight computer. "SEC3" refers to the computer that controls the spoilers and elevator computers of the plane.
Edited to add: I'm assuming those numbers are times? Are they before or after when air traffic control tried and failed to contact the plane?

From the video that was posted upthread, the plane was okay at zulu 00:27, and at 10,000 feet three minutes later at zulu 00:30.
If everything was okay aside from smoke in the bathroom in the first minute (00:27z), why didn't the pilot send a mayday - or did the fact that they were transitioning between airspaces mean the mayday was lost? Could that happen?

The first rule is FLY THE AIRPLANE, anything else is secondary.
In total, it seems to suggest a fire on-board the aircraft.

Aviate, Navigate, Communicate.
Also, given the smoke alerts it is possible that the crew became incapacitated at some point.
