Here is a ‪#‎MH370‬ situation update from Flightradar24 because of the many questions we get.

The ADS-B transponder of an aircraft is transmitting data twice per second. FR24 saves data every 10-60 second depending on altitude. On cruising altitude data is normally saved once per 60 seconds. By analyzing all our databases and logs we have managed to recover about 2 signals per minute for the last 10 minutes.

The last location tracked by Flightradar24 is
Time UTC: 17:21:03
Lat: 6.97
Lon: 103.63
Alt: 35000
Speed: 471 knots
Heading: 40

Between 17:19 and 17:20 the aircraft was changing heading from 25 to 40 degrees, which is probably completely according to flight plan as MH370 on both 4 March and 8 March did the same at the same position. Last 2 signals are both showing that the aircraft is heading in direction 40 degrees.

Today there are reports in media that MH370 may have turned around. FR24 have not tracked this. This could have happened if the aircraft suddenly lost altitude as FR24 coverage in that area is limited to about 30000 feet.

FR24 have not tracked any emergency squawk alerts for flight MH370 before we lost coverage of the aircraft. Playback for flight MH370 is available on

The poor coverage on the area may explain the changing headings on that position due to signal degradation.
The lack of of coverage below 30000 ft may explain the loss of contact if the aircraft has descended 5000 to 6000 ft and that descent is possible when considering Flight Radar has only a few and spaced signals on the last minutes.
The major question is if the descent was due to a technical problema or ilicit interference ... and this could make a big difference on defining the search area.

Note : I'm an Air Traffic Controller and often compare data on my radar screen with the FR24 App on iPhone or iPad and accuracy is amazing up to the point where coverage decreases. (and I also have a stand-alone ADS-B receiver).

So no radio calls, no squawk change, no ACARS messages, no major ADS-B change in speed/altitude in 60 secs. Sadly, it sounds like something immediately catastrophic took place...

There's something very fishy about this flight.. Nearly every single commercial aircraft catastrophe has been found, black boxed, ADS-B'd and solved.. Even TWA 800! But the fact that this is just mere several miles off shore with ATC tracking data, lat/long coordinates, and track and cannot be found strikes new options to me. I think THEY know where it is, but WE don't.

How come last nights flight (8th March) and the one listed on flight radar on the 1st March both lose signal at the exact same points as the 7th March flight (as it turns from 25 degrees to 40 degrees heading) before signal is picked up again near southern tip of Vietnam. I.e the plane could have gone down anywhere in between that blacked out zone. Also some of the days historical data on FR24 shows the full route across the gulf of thailand in signal with no blackout, is this due to atmospheric conditions ? So the search shouldn't necessarily be at your last co-ordinates but somewhere between there and the coast of vietnam on it's usual flight path?? It takes roughly 20minutes of flying to get across that black out spot and the last ATC contact was supposedly received at 1.30am KL time. So in distance terms maybe 110kms south west of southern tip of vietnam?? http://www.flightradar24.com/data/flights/mh370/

i would think if a plane blows up mid air the instruments would give off quite a few strange readings. What i find interesting is given the fact that they know exactly where it went off radar, why they haven't found it yet.....Given the fact that air france was off radar and in a dead zone and they still managed to find its wreckage in 2 days.

The Guardian

"The Guardian’s Tania Branigan has more detail on the movements of the two suspect passengers who boarded the missing plane using stolen passports.

Both passengers used Thai baht to purchase their travel tickets on 6 March, a day before the flight took off from Kuala Lumpur destined for Beijing.

The pair, who booked tickets with consecutive numbers, were due to fly to Beijing, then wait for around 10 hours before flying to Amsterdam. "

I think this is suspicious.... frown emoticon

Thank you for the update. Seemingly, FR24 data is more informative and explanatory than the news. This is the sort of info that should be offered to the families. That would, at the very least, keep them from feeling like they are not being told anything. Sometimes, even confusing information can be comforting, especially while the plane is still missing. My thoughts and prayers are with all involved tonight. Kudos, FR24.
