Egyptair Flight MS804 Disappeared from Radar [New conclusion]

[Skyring]

OK -Here's a forum I use a lot for stuff like this. Still a lot of speculation ,but at least it is mainly by pros . Here's the link to the relevant thread
EgyptAir 804 disappears from radar Paris-Cairo - PPRuNe Forums

Thanks. That was my next point of call. These are (mostly) people who know what they are talking about. They'll also likely have access to information sources beyond mainstream. I watched one news item which showed footage of a variety of Boeing and Airbus models in their report. Hard to have confidence in such folk. PPRuNe is probably about as good a source as it gets for most of us.

While this has been done now, reporting the first (or any) post alerts moderators much more effectively than a comment that can be overlooked.

Shall remember that - never had to do before. :mrgreen:

From a cargo ship apparently?

YouTube also has the same video "from residents of a Greek island". The link has since been pulled from PPPRuNe.

Another useful source of information is the Wikipedia article at https://en.wikipedia.org/wiki/EgyptAir_Flight_804

All information is sourced and there will be a lot of editorial eyes on it to make sure anything unsourced or flakey is removed.

Given the posters other videos, and disabling of comments, I'd say its a fraud... and attempt to get traffic (which youtube pays you for)

That youtube video does not seem likely to be of a plane going down. The change of angles/speed do not coincide with an object at 500 or so knots at 30000+ feet being filmed from the ground - it was either something much closer to the ground, or something doing about Mach 10 at altitude. It was also on a fairly straight trajectory - so I doubt the plane would have dropped to <10000 feet while on fire yet retain control without some sort of mayday call.

You need to get mayday calls out of your mind. They have virtually zero priority within the coughpit.

I wondered why 3 security personnel are required for flights into Egypt?

On an RJ 787 not so long ago between HKG and AMM there were at least 4. Don't ask me how I could tell.

Interesting and no I won't but you are observant of human ? behavior?

Ok you twisted my arm. They meet in J,wear the same ill fitting suits, adjourn to the galley for a smoke (regularly), stare at each passenger, then take their seats. Call me observant.

Did you say smoke? I thought that smoking was banned stopped but obviously not :shock:

Apparently debris just been located off a Greek island Karpathos ?

They would have less than 15 seconds (time of useful consciousness) to put on their oxygen mask, if there was sudden (explosive) decompression.

That's an eternity...

"During a press conference later in the day, Greek Defence Minister Panos Kammenos said that, based on radar data, Flight 804 veered off course shortly after entering the Egyptian Flight Information Region (FIR). At an altitude of 11,000 metres (37,000 feet), the aircraft made a 90-degree left turn, followed by a 360-degree right turn and began to descend. Radar signal was lost at an altitude of about 3,000 m (10,000 ft)."

Sounds almost like onboard activity than bomb?

There needs to be more information on this claim. Radar resolution is often measured in miles, so it would be interesting to see how these turns were resolved, and their time frames.

 

[juddles]

I know nothing of Egyptian radar, but that detail does seem very precise (ie not reliable)

 

[juddles]

jb, how long does it take to descend 27000 feet at a "controlled" (ie not falling) but rapid descent?

 

[jb747]

You should be able to do about 10,000 fpm, at full speed brake and max speed.

The issue is the time it takes to turn. The aircraft don't have masses of g available. A 360º turn would take multiple minutes.
