Easy to understand why they didn't want to be stuck in Manaus with an engine to replace...

Is that such a big fault not to resume the flight on two engines, particularly on a freighter ?

Well, British Airways can manage LAX to Manchester with an engine shut down, so what's the problem?

The problem is that Bogota is at elevation of about 8500' and that is actually the bottom of the valley.
It's in the middle of the Andes while Manaus is probably as flat as a pancake; don't they have cold beer there?

Since the crew was informed that parts hit the ground and Brazil has been know to jail crew involved in accidents, they may have thought getting out of the country was the best thing to.

When they say "it lost part of an engine", which bit was actually left on the aircraft?

Looking at the blade hanging on that ladies wall I'd hazard a guess at a turbine disc letting go...not unusual if it's a GE CF6.

BTW looking at the foggy windshield of the car in Machaca's photo's, I wonder what that guy was doing when it was hit by the engine

I appreciate an aircraft can fly on just 2 engines but what about the change in C of G with such a large piece missing ?

It must have been trimming at the limit.

GYS

No idea what he was doing BEFORE the engine came down (good point, Paradise Lost, which part is left on the aircraft) but I bet ya I can guess what he did when the engine landed beside him.

Turbine disk failures have been very rare even in that machine

Turbine blade failures not nearly as rare in most machines.

The CF6 has had a number of events that look just like this (about 1 every two years)

there's one more picture

G1 - O Portal de Notícias da Globo - GALERIA DE FOTOS - Veja fotos de parte da turbina que caiu em Manaus

#4 in the set of 6 pictures isn't copied above

Look at the chunk out of the roof and wall of the house, you can see the engine was still moving sideways when it hit the ground.

Nice pictures, sort of looks like a shuttle "pod". Been through Manaus and Bogota many times. I want to say rwy 33L/R faces mountains and is usually landing / take off direction. Heavy engine out would suck, I don't see why they can't get a ferry permit back to KMIA, should not be a problem empty.

Never seen a CF-6 shear off a turbine section/tailcone. Must have been last few stages. They are known for spitting blades "coreing out".

According to an official statement, the tower contacted the crew after hearing a loud bang during the take-off. The crew denied any anormality. After being informed that parts of the engine from the plane were found, ACC contacted the crew once more. Only then they informed that they had shut down one engine.

If that is what the crew did, you don't get surprised at how some American airlines and their operators are considered in certain parts of the world...this is truly appalling!

Considering the distance, the high altitude landing at Bogota, and the alt landing spots (nil) in between, I would think it takes quite a pair to make the decision to continue after losing one out of Manaus...
