Airplane Traffic at 18:22 UTC (Last Air Defense Radar Point of MH370)

Hover over image to open it in a larger view.

I captured a screen shot of all of the airplane traffic at 18:22 UTC on FlightRadar24, and used the Preliminary Report Map Showing MH370’s Flight Path to add the flight path and approximate locations for MH370 at18:01:49 UTC and 18:22 UTC.

I also added certain waypoints and airplane call signs, as well as MH370's last approximate transponder location at 17:22 UTC.

At 18:22 UTC, UAE343 was flying at 34,000 feet in close proximity to where they identified MH370 as being at that same time.

Notes:
Inmarsat plot satellite data times are estimated from their plot (see Reference [1]).

Every 1 hour interval at xx:41 is based on MH370 takeoff time and "ping handshake" being every hour. It corresponds to data point times shown on the Inmarsat plot

Every 30 minute interval at xx:11 (and xx:41) is based on Rolls Royce engines sending data every 30 minutes. It corresponds to the 00:11 data point time shown on the Inmarsat plot

Pulau Perak sighting at 2:40am

Hover over image to open it in a larger view.

On Mar 11, 2014, Malaysian General Rodzali Daud was quoted as saying that at 18:40 UTC (2:40am) an "unknown aircraft" was detected near Pulau Perak, flying at 29,500 feet. He subsequently denied saying that.

At 18:33 UTC, KLM836, another 777, passed very close to Pulau Perak, flying at 30,000 feet.

Information about airplanes in that vicinity at 18:33 UTC:

KLM836 777-206(ER) 30,000 ft
UAE405 777-36N(ER) 33,300 ft
UAE343 777-36H(ER) 34,000 ft

One article about Daud's statements can be read on Reuters.

The screen shot was captured at FlightRadar24.
