It's trivial.

Losing in a twin is a lot more serious.

But aviation, these days, the problem in aircraft tend to occur with passengers.

They get sick.

They get on with drugs, alcohol, stress.

The business class passengers generally cause more commotion and trouble than the economy passengers.

They come on more stressed.

Maybe there's a problem with wars.

Politics have to divert around airspace.

Maybe there's a problem with the weather.

I'm just saying that engine failures that used to be common on aircraft are not common anymore.

And as I said, one in eight twin pilots will ever see an engine failure in their whole career.

Okay, so a little oil pipe that was to take oil to a bearing mount inside the most inner part of the engine.

That pipe had been manufactured incorrectly.

It cracked because of vibration.

Oil went into a part of the engine that should not have had any oil into it.

Sitting at about 800 degrees Celsius, the oil catches fire, heats the driveshaft,

makes it soft, and the turbine that has been taking 50,000 horsepower out of the air, it now rips itself off that shaft because the metal's weak.

That turbine weighs 160 kilograms, high tensile steel.

Physics say it breaks into three pieces, and ours broke into a few more.
