The video of the plane flying before the crash looks like the flaps are not extended. 

Is that even possible on a modern airliner. I thought they would have all sorts of warnings going off.

BBC has the best coverage, it appears there are no survivors from the flight, and the death toll for civilians on the ground will be in multiples of 10. The video clip shows a Dreamliner struggling to gain altitude, slowly sinking into the village and producing a sharp nose-up shortly before crashing. The aircraft exploded on crashing, it appears the only major section left is the tail, stuck in the top of a building.

 

The aircraft crashed into a medical educational centre, with many medical trainees living in flats that have been seriously damaged and destroyed. Aircraft misconfiguration, crew mishandling of controls, high temperature on takeoff (it's reported it was over 40°C in the area when it took off), and also reports of the aircraft taking off a long way down the runway, meaning inadequate liftoff distance. The crew capabilities are going to come under examination, most surely.

First ever fatalities recorded for the 787 Dreamliner, will be something simple that caused it most likely.

sure does look like the flaps are retracted and with the gear still down could it be as simple as wrong lever moved?

Or in-fact were the flaps and spoilers ever set prior to takeoff. (Looking at the cctv footage BrendAn put up)

Time will tell I guess, very sad for the victims and their families.

The Captain made a Mayday call saying he was losing power - and the failure to climb, and then slowly sinking, is indicative of power loss. What the reason was behind the power loss will be the focus of investigations.

Could it have been the FO mishandled power settings and the Captain failed to notice any incorrect settings?

Birdstrike on both engines has been suggested, but I see no birds in the vicinity, and no indication of flameout in the form of flames or smoke from engine exhausts, as one would expect from birdstrikes.

 

There was one survivor out of all the aircraft pax and crew, a British-Indian passenger seated in 11A, who walked away from the destruction with facial injuries and some chest injuries.

He said he came to after the crash surrounded by destruction and bodies, and simply got up and walked off. Talk about luck, he should buy a lottery ticket. Total deaths are close to 300, one of aviations worst disasters for a long time.

I agree about power loss. Even if the flaps were retracted and the wheels down I would have expected the aircraft to at least maintain altitude under full power once it was at 400 feet. The initial climb out was reasonable especially in 40 deg heat & fully loaded with full fuel.

Retracting the flaps would UP the stall speed by about 50 Knots from  the TO setting. There was no assymetry and losing power would be very unlikely to be EVEN on Both engines That plane was stalled and draggy. The rotation and lift off was Normal. Why wasn't the GEAR retracted on a "positive climb " call. A DH Trident went in that way in England . Fell out of the sky with all three engines operating. unable to accelerate to the clean speed needed even though the gear was UP. Nev

There has been comment about the ram air turbine being extended, that usually only happens with multiple failures of systems. In the original video the noise of the RAT (sounds like a Harvard prop on take off) is heard. I have also seen mention of possible software failure. With so many 787's flying you would think they will work out pretty quickly why this accident happened.

Airliners usually fit the CVR and FDR in the tail section, the tail section looks quite intact and accessible.

I cant see why there shouldnt be a comparatively quick resolving of what caused this

i heard on the radio that  aircraft flew out of melbourne earlier this week.  nothing important, just thought it was interesting.

Hopefully most of the people in the hostel were at work

Unfortunately, all the medical trainees and teachers were having lunch in the buildings as the aircraft landed on them.

that is horrible

this is the first dreamliner crash after 14 years of service.   they are still saying wrong configuration for take off.

The aircraft tore the top storey off the building it hit first (the one with the tail stuck in it), then the exploding remnants of the aircraft flew on for many hundreds of metres, damaging buildings further on, after travelling across a small open area.

Wreckage fills the streets all around the fire damaged buildings. I really am amazed there wasn't hundreds more casualties on the ground, knowing how populated India is.

Uncommanded rollback of throttles? Or did the FO make an alteration to power settings accidentally, when he was about to raise the gear? All the indications in the video are, the power was reduced at about 500-600 feet.

Pictures I've seen show members of the public wandering around the wreckage with no attempts by the authorities to kep them away.

There will much Carbon fibre floating about which on top of the usual toxic crap found at a metal airliners crash site will probably cause a few more deaths in years to come.

I really dislike the use of Carbon fibre composites, Once its in a resin build up you cant just recycle it like aluminium...will be the next century's Asbestos IMO, horrible stuff
