Some of the conjecture by so-called media "experts" is just stunning in its nonsense. It is hard to believe that these statements are being printed and given credence.

Experts say the absence of any crash transmission means the experienced former airforce pilot Captain Irianto may have executed the perfect emergency landing before being the plane was overcome by high seas and sank.

While the hunt is on for the black boxes, several aviation experts believe the absence of any usual crash transmission data means the plane could have touched down safely with all 162 people on board.

After leaving Indonesia early on Sunday, the Airbus A320-200 disappeared over the Java Sea during a storm but the emergency transmissions made when planes crash or are submerged in the sea were never emitted.

So flight experts now believe it's entirely possible that experienced former airforce pilot Captain Irianto may have safely landed the plane on water - before it was overcome by high waves and fell to the bottom of the sea.


Indonesian aviation analyst Gerry Soejatman believes the aircraft rose up as fast as a fighter jet and then dropped back into the ocean almost vertically into the water.

And the extreme weather which Airbus 320-200 encountered meant the pilots were helpless to save the passengers and crew on-board, Soejatman told Fairfax media after he examined figures leaked from the official air crash investigation team.
In contrast, aviation expert Peter Marosszeky, from the University of NSW, told the Sydney Morning Herald that the extremely low speed of the aircraft’s descent - as low as 61 knots - would suggest the plane was heading almost straight down, explaining why it has been found in water just 10km from its last point of radar contact.

Mr Marosszeky surmised that a climb rate of at least 6000ft a minute would indicate a “severe weather event,” because that rate of climb was a ‘domain for jet fighters.’

He said “It’s really hard to comprehend [the plane acted in a way] bordering on the edge of logic,” as it plunged into the water “‘like a piece of metal being thrown down.”

Mr Soejatman believes the crash occurred because the aircraft was caught in a severe updraft, followed by an equally severe ground draft, with the leaked figures showing that it climbed at a staggering rate of 6000ft to 9000ft per minute.

The aircraft then fell at 11,000ft a minute, with bursts of up to 24,000ft – in marked contrast to regular circumstances, when a plane would climb between 1000ft to 1500ft on a sustained basis, gaining 3000ft in a burst.
Dudi Sudibyo, a senior editor of aviation magazine Angkasa, said: "The emergency locator transmitter (ELT) would work on impact, be that land, sea or the sides of a mountain, and my analysis is it didn't work because "there was no major impact during landing." "The pilot managed to land it on the sea's surface."
