MH370 had to have human interference

The disappearance of Malaysia Airlines Flight MH370 could have only involved human input, according to two aviation experts.

A senior Boeing 777 captain and a former crash investigator agreed that given the information outlined in the preliminary report issued late last week, "human input was essential" for the MH370 to end its flight in the Indian Ocean.

"We are not dealing with an out-of-control plane - it is impossible for the Boeing 777 to fly this course by itself," the captain said.

The plane's flight path shows multiple course changes and altitude changes, according to Malaysian authorities.

"To change course requires the pilot to either disengage the flight management computer and dial in a new heading to the autopilot/flight director or fly manually," the captain said.

OFFICIALS MEET TO DISCUSS SEARCH

According to Malaysian authorities, the plane went up from 35,000ft to 39,000ft before descending as low as 5000ft.

When it ran out of fuel, it was at 30,000ft, about 1000km west of Exmouth.

The Malaysian crash investigators have released the first map of the flight path of MH370.

It shows the exact track as detected by Malaysian military radar, then the location of the satellite pings as picked up by Inmarsat.

There are six pings, then a final partial ping a few minutes later.

The black box towed pinger locator, deployed by the Australian ship Ocean Shield, picked up four signals in the location of highest probability as suggested by Inmarsat early last month. According to a former crash investigator, when MH370 ran out of fuel and, if nobody was in control, the Boeing 777 would not have glided down slowly.

"There are a variety of scenarios," the former investigator said.

"It could have gone into a spiral or maybe a flat spin.

"Another scenario is an aerodynamic stall with a nose pitched up and then a roller coaster ride down." 'It could have gone into a spiral or maybe a flat spin.'" Former crash investigator
