With autopilot engaged the aircrafts computer would have compensated for any difference in the filght of the aircraft by auto trimming.

I was an aircraft mechanic in the Navy. We had an idiot remove a panel on the tail and not retighten the zeus fasteners. Shortly after takoff the panel flew off of the aircraft. The only clue the pilot had was that the aircraft was "pulling" to one side and his airspeed was low compared to his throttle. Luckily the panel was out of the direct airstream. He immediatly reduced throttle and landed. Even doing this a huge section of the skin of the aircraft was peeled back. If the pilot hadn't of been paying attention the rear of the aircraft could have failed.

So, someone places a small bomb in an unpressurized void on the aircraft. This small charge detonates leaving a hole in the aircraft that is directly in the airstream. The air enters the aircraft at 400 plus mph and begins to break the aircraft apart. The autopilot trims the aircraft to compensate for the change in flight characteristics. Eventually enough skin is compromized that the tail breaks off of the airframe. G forces prevent the pilot, co-pilot from making a mayday call. The tail winds up landing first away from the rest of the aircraft. There wouldn't be major damage from the bomb that would be visible with the naked eye. It would take a chemical analysis of the reckage to check for bomb residue.
A320 series has no unpressurized cargo holds.

Sort of like in case with TWA 800.

P.S. What did you do with "an idiot"? You knew who he was, right?
She went to captains mast. She was demoted from a 2nd class petty officer to an airman, restricted to quarters for 6 months, and lost a half months pay for 2 months. She eventually wasn't allowed to re-enlist.

If that aircraft had of crashed she could have caused the deaths of the pilot, co-pilot, plus who knows how many people on the ground.

Even so, there are plenty of spaces that the grounds crew has access to that are not pressurized. In the US anyone with access to the flight line has to undergo extensive background checks, but you never know in foreign countries.

The grounds crew is the last ones to touch an aircraft, it would only take a device the size of a brick to bring down an airliner if it is right on the skin. That type of device can be concealed easily.

This may be a silly question, but I'm not a pilot or airplane person. Where do the G-forces come from in this scenario? Is it because the plane is slowing suddenly? Or speeding up because it's falling?

Is there any more information about the communication the pilots did make? (I thought originally the pilots had reported a technical problem?)

8 pm Russian news

1. showed large crack in rudder picture (video actually), from May 2015, same airplane, during take off.
2. showed some tail section areas that were twisted from inside out, like during explosion from the inside
3. some bodies show burn marks
4. seconds before fall, registrators recorded "non typical noises" inside the airplane, without clarification what those were
5. American spy satellite apparently recorded a "light flash" in the crash area. Not clear if it came from the plane or from the crash site

Not quite relevant yet..

Each family of a person that died in the crash will receive a 2 000 000 ruble donation from government plus 25 000 for funeral costs.
62.58 rubles = 1 US $

When you slow down there is a huge amount of G-force, it is almost like hitting a wall. Going from over 400 mph to 160 mph in 2 seconds is a ton of G-force. I have landed on an aircraft carrier in a C-2, and you go from about 150 mph to a stop in about 2 seconds. You have to physically prepare yourself for that G-load. You literally can't breath, your arms will fly forward if you don't hold your seatbelt.

So lets just imagine there you are hitting cruising altitiude, you set the autopilot and are talking with your copilot and then bam, a small device explodes ripping a hole in the skin of the aircraft. You get a depressurazation warning and then the force of the air outside rips the tail off of your aircraft. If not belted in the pilot would fly into the instrument panel with enough force to kill him instantly. Even if buckled in he would momentarily loose control and his arms flailed in front of him and his hed snapped forward with extreme force. At this point the autopilot would increase throttle as it tries to correct the airspeed. With no tail to guide it the plane acts like the paper planes we made as kids. You remember how they would go down and then up and then one way and then another. Well in an aircraft each climb, decent, and turn would place a huge amount of G force on the occupants. Even with an oxygen mask right there, the pilot or co-pilot, if they survived, may not be able to reach it. It is like trying to tie your shoes on a roller coaster.

Lukily the passengers would have all passed out within 10 seconds and been asleep before they ever hit the ground.

Significant update! Britain delays all British-bound flights from Sharm al-Sheikh pending investigation of security procedures on the ground there:

No 10: 'Explosive Device' May Have Downed Plane

Very likely based upon new intelligence. Focuses upon possibility of device placed on board.

So for the tourists stuck in Sharm al-Sheikh are they going to bus them to Cairo or send a flotilla for them?
