Flight to Gatwick crashes near airport in Ahmedabad, India,

But why was the RAT deployed? If the plane was overweight or not at takeoff trust etc… the RAT wouldn't deploy.

Its the complete absense of engine noise in that clip that would make you think the engines are at idle or not running at all. You'd expect them to be at close to full thrust at that point.

The noise in the video does sound very much like the RAT when compared to similiar videos of the same plane with the RAT deployed however obvously there were different audio equipment and distances to audio source involved etc.

That said, at this point the investigators whether it was deployed and why it had been deployed at this point. They may not and probably don't yet know the root cause of the reason for whatever caused the RAT to be deployed to have failed in the first instance.

It's an awful awful crash but probably could have been worse as there are more populated spots off the runway.

As with the majority of these types of incident, there'll be more than one "reason" that this happened and it took all of the holes in the Swiss Cheese to line up to lead to the disaster.

Believe it or not, there is bacteria, yeasts and fungi that can thrive in jet fuel.

At that time (15th June) many theories were swirling around on the internet, and I picked up on that one to add to the list of possibilities. Other theories included who pilot error (with the flaps lever being mistaken for the throttle). Another theory was that either the pilot or the Co pilot shut off the fuel supply by mistake!

Then there was the bird strike theory, or maybe the plane was too heavy, or the the electrics failed?

So here we are going into July and nothing official has been released yet, no nothing from the black boxes!

Taking a while isn't it?

Why the delay?

Would it normally take this long after a crash to release some info?

Alarms are typically silenced on take-off. This is to avoid distracting the pilots.

The images show both the flaps fully extended, and the landing gear down. This is perfect take-off position.

Landing gear retraction would usually be started by then, or at least the wheels put into Front-Wheel-up position so it could be retracted. Planes can fly just fine with it down, but it's another pointer to a total power and hydraulic failure that it didn't happen.

The pilots had no ability to control that plane. The RAT doesn't generate enough power to fly the plane, after a few minutes it can give enough power to bring up controls and do an engine restart sequence. But that only works if they already have enough height to glide.

There was no bird strike. There was no yaw and as engines are on different fuel lines, I think fuel would be unlikely to impact them both at the same milli-second.

I don't remember if the pilots gave a mayday, but if they did, they were out of options. Mayday is the last option in aviate, navigate, communicate.

And hitting a medical college full of students is so tragic also. I think about is how proud my indian colleagues were of their sons and daughters who had worked hard enough to get into med school.

I lean towards computer issue.

Computer issue is something that should never happen, not like this. TBH I would rather consider inadvertent or even intentional human action before considering computer issues.

Fail safe is the key word, mentioned in one of those two articles. The generators going in fail safe mode probably means they will continue to generate a reduced amount of power which could lead to some of the systems powering down but not a catastrophic failure.

And some parts of the world are lax in pilot training and airplane maintenance.

The last western airline fatal crash I remember was the one lost over Pacific which was an Air France Airbus in 2009.
