Which begs the question. What is the procedure in such scenarios? I'd think that in the absence of reliable information, erring on the safe side (i.e. delay the flight) would be the standard?

Odd that BOTH ended up there, but might also support the huge wind shear suggestions. Wind was coming from starboard side. Video is being taken from starboard side. It appears there was lift off but it could just be the right wing gaining lift due to the increased wind speed. As soon as they lost that increased wind speed the aircraft overcorrected and lost lift causing it to slam back down. with both engines being dropped.
Who has final say on departure? Would the tower revoke clearance for a take off based on radar indications? What was going through PIC and FO minds? Surely they saw that weather. Probably didn't even have enough visibility to see the end of the runway based on that video.

I wouldn't call this intact.
That plane will never fly again. It's totally wrecked.
Just hope for the best for everybody that was on board.
He said the tail. he was correct!

Are there any precedents to this kind of accident (that the plane takes off and immediately after take-off slams to the ground due to the weather and apparently not any mechanical failure)?

Aug. 15, 1975 at DEN (Stapleton), Continental 426 (B-727-200) encountered wind shear after lift off and settled back into the ground. Thunderstorm in vicinity of the airport at the time. Everybody survived but aircraft was damaged beyond repair. Seems very similar to this accident except the Continental didn't catch fire.

“It’s not a miracle,” he said. “This is a design-based accident that should be survivable. We’ve worked long and hard in the industry to ensure that an event like this is something that people can walk away from, that the seats don't slide forward on impact, that limbs are protected. The safety of passengers is no accident.”
He added: “The grassy area you see around an airport is not just wasteland, it is deliberately kept free of obstacles such as ditches or power lines. It is designed to allow a landing that people can walk away from.”<<

Cannot be stressed enough!

Both videos have a high pitched squealing sound - is that people screaming, or is that something mechanical? On my computer, it's hard to tell. It almost sounds like some kind of motor whining, and I'm just wondering what it is.
We really still cannot jump to conclusions about the weather being the direct cause of the accident. Since the plane doesn't seem to have gotten out of ground effect, it could be an early liftoff (given the conditions), engine failure *combined* with weather (that would have otherwise not been a problem), or a number of other things. It's rare for any crash to be down to one cause, so I'd be surprised to see the eventual cause listed simply as "microburst".

As I alluded to earlier, the cause these days is never just "windshear". Windshear is a known quantity; we understand it, we have instruments to detect it (if installed, but if not, then that's potentially the root cause). If a plane crashes due to windshear in 2018, then windshear is probably not the cause any more than square windows or unattended baggage would be. It's just not an unknown thing at this point; it's something that everybody in aviation understands. Lack of proper equipment to detect it, a decision to take off in known windshear conditions beyond the airplane's capabilities, a mechanical issue that coincidentally happened in windshear conditions, or other issues would be the root cause.
We'll see... clearly they were taking off in bad weather, but lots of planes take off in bad weather. Something caused *this* plane to crash. Whether they really shouldn't have been taking off (which would be the cause in itself) or something else happened coincidentally, we'll still have to see.

One of the things we both pointed to was whether the gear was up or not. If not, and it had remained out, we both feel that the possible "slamming" of the aircraft back into the ground would mean that the gear took most of the impact allowing the airframe itself to remain mostly intact, this allowing escape/evac.
Anyone know anything about this? Just a thought.

Unless the crew were severely breaking the rules, they would have to achieve positive climb rate before calling for gear up. There's no way that was achieved in the very brief time they were airborne.
