WHY DID MS804 COME DOWN WITHIN MINUTES OF ENTERING EGYPT AIR SPACE?

MS804 had just entered Egyptian air space and had been transferred to Egyptian air conrol, and had just started to descend, when it came down.

If the cause was terrorism, then what kind of attack was this?

1. if a suicide bomber then why wait so long before detonating the bomb? Is Egypt the real target? And if the real aim is Egypt then how did the bomber know he/she was in Egyptian air space?

2. if a bomb was planted on board then what kind of bomb? And why was such a bomb selected? If it was timed then it looks like it was designed to detonate in Egyptian air space. And if so, why?

Is Egypt the target because of its collaboration with Israel in isolating Gaza?

3. if a bomb the who planted it? I heard Pan Am 103 mentioned a few times yesterday, which was brought down by a rogue faction of US intelligence and was eventually blamed on Libya.

Was this a warning to France? Egypt? Was any potential bomb planted by a rogue intel faction detonated so that the debris would fall in to the deep blue sea rather than on land where fragments of any bomb could be recovered?

Or maybe the pilot went nuts?

Or maybe it was taken over by remote control?

If Islamic State have claimed responsinbility then why is the MSM ignoring such a claim when such a claim would provide further reason to attack Syria?
