The text message sent by Malaysian Airlines to family members of missing passengers was “sickening”, according to the wife of an Australian missing on flight MH370.

Danica Weeks told 60 Minutes last night that her husband Paul was about to start a dream job in Mongolia as a mining engineer.

When the Perth woman received a text message from Malaysian Airlines saying that all passengers on the flight were presumed dead, she was “sickened.”

“(I was) just sickened, sickened that someone would actually send me a text message to say that my loved one was dead.

“This is my husband, my loving husband, father of my children, and you send me a text message?”

The text message – sent on March 24 – read: “We have to assume beyond reasonable doubt that MH370 has been lost and that none of those aboard survived.”

Ms Weeks is still trying to work out how to tell her three-year-old son that his father is missing.

More objects found at sea

An Australian navy vessel is heading out from Perth with special equipment able to detect signals from the black box recorder on missing Malaysia Airlines flight 370.

The Ocean Shield was due within the Indian Ocean search zone early on Monday to join an international array of ships and aircraft scouring the seas for any sign of the lost plane.

It’s dispatch comes with one of Australia’s P-3 Orions spotting four orange-coloured objects at sea, each more than two metres in size.

The co-ordinates and images of the items, the latest to be sighted, were “of interest” but would need to be analysed, Flight Lieutenant Russell Adams told Fairfax Media from RAAF Pearce base after returning from an 11-hour mission on Sunday night.

A GPS buoy had also been dropped in the area of the sighting, Lt Adams said.

Similarly, the specialist US Navy technology on board the Ocean Shield will not be able to detect the “pinger” within the plane’s black box until a more confined search area is identified.
