Spirit AeroSystems and Boeing are close to reaching a funding agreement that would give a cash lifeline to the struggling Boeing supplier, an industry source familiar with the matter said.

Qantas said in a statement on Friday that there had been a "contained engine failure" on the Boeing 737-800 aircraft.

That big bang as the wheels were leaving the ground and the shudder — that was like nothing I’ve ever felt,” one passenger said.

A Qantas plane made an emergency landing after returning to Sydney Airport in Australia shortly after taking off after an engine failed, the airline said.
