Egyptair Flight MS804 : Expert Says Rapid Decompression Might Have Set Off Smoke Detectors

by Scott Creighton

UPDATE:It looks like the right front and side windows were blown out, most probably from inside out,” European airline pilot

Just a short note.

The MSM is focusing solely on the ACARS report that smoke detectors went off in two locations right behind and underneath the cockpit just before the plane made a “jerky and sudden” 90 deg turn to the left and then plummeted into the Mediterranean Sea. They claim this means either a terrorist attack inside the plane or a mechanical malfunction caused a fire on-board and that is what brought down Egyptair Flight MS804.

As is usually the case with the MSM, that is not entirely accurate.

Turns out, sudden decompression can cause smoke detectors to go off on a plane.

The Telegraph reports that the signals likely indicate an internal explosion that could have blown out windows from the inside out and started a fire on board. An external explosion, like the missile that brought down Malaysia Airlines flight MH17, would have caused more alarms to trigger.

Although industry analyst Robert W. Mann tells The New York Times that a fire onboard was not necessarily the only way to cause the automated messages.  “The messages could also have been prompted by rapid decompression of the aircraft, which can produce condensation that the plane’s sensors could mistake for smoke,” Mr. Mann said” CS Monitor

Notice what the Telegraph did? They deliberately tried to undermine the theory that the plane could have been hit by a missile like Malaysian Airlines Flight MH17. I wonder why they would do that.

Well, they would probably do that because more and more the information we are getting is making it look like a missile brought down Flight MS804 and not “terrorism” or a mechanical failure of some kind.

Rapid decompression could have caused those sensors to go off and the fact that they were both located near the cockpit says a lot, especially when you consider what happened with Malaysian Airlines Flight MH17. Here’s a little visual aid to help you guys remember.

The Dutch Safety Board study concluded that a ground based missile fired from a BUK system detonated on the left side of the cockpit, shearing off the nose of the plane and causing it to crash.

In this case, the ACARS information is clear: something happened to shatter a window in the cockpit of the aircraft first and THEN there was “smoke” reported in the bathroom and avionics compartment directly below the pilots.

Shattering the window would cause instant decompression in the cabin, bathroom and avionics compartment.

from AV Herald (original source)

On May 20th 2016 The Aviation Herald received information from three independent channels, that ACARS (Aircraft Communications Addressing and Reporting System) messages with following content were received from the aircraft:

00:29Z 2200 AUTO FLT FCU 2 FAULT
00:29Z 2700 F/CTL SEC 3 FAULT
no further ACARS messages were received.

Early May 21st 2016 the French BEA confirmed there were ACARS messages just prior to break down of communications warning however that they are insufficient to understand the causes of the accident until flight data or cockpit voice recorders have been found. Priority as of current is to find the wreckage and the recorders.

Also keep in mind, the Greek military released information that the plane suddenly turned 90 degs to the left, which would make sense if a cruise missile detonated to the right of the cockpit. Earlier I had theorized that the pilots may have been attempting some form of evasive action with that turn. Could still be possible. Will have to see what the time frame looks like.

However you look at it, this new revelation from Robert W. Mann seems to suggest a timeline that makes more sense than a fire on board. A fire on board would not shatter windows in the cockpit before setting off smoke alarms. The fact that the window was broken first and THEN the detectors were activated is a strong indication that something explosive occurred OUTSIDE the cockpit.

Last month I had hoped I wouldn’t have to do a donation drive this month, but things don’t always turn out the way you expect them to. If you can help with anything, it would be appreciated. Thank you very much.

  1. The Truth Behind the Demise of EgyptAir Flight 804 Uncovered?

    Certainly the deployment of also a French nuclear submarine to the
    region cannot possibly have anything to do with the search for flight
    804, after all the wreckage and debris have been located already (first
    item of today’s update #26) and ridiculously meaningless photos of
    “debris” have been released.
