    they would have been better off shutting down and locking-up the brakes and trying to stop

    I'm confused - were they attempting to land or take off? It seems as if they were trying to take off and didn't get lift for some reason (weight?)...

    Prayers to those on board, terribly tragic. :(

    Trying to take off. It's apparently a spectacle watching that plane try to take off each time because it barely takes off in time. Kind of leads you to wonder if there's a pattern of the plane being overloaded.

    In one of the videos you can see flames coming from the engine after it goes past the runway (likely hitting something). I can't imagine that helped their case any.

    Tragic. :(

    It was a cargo flight taking off.

    The first thing i thought of was flaps/slats because ive seen iy before on aircrash investigation. Looks to be extended to me and the engines sure are humming.

    RIP to the crew.

    They were taking off. That flight was a local favorite to come and watch because it was always so close to the fence on takeoff-- there are other videos on youtube from days when they made it.

    But, that close (and probably way closer than it should have been), it wouldn't take much of a mistake to bring ruin. Maybe they were a little bit heavier than usual, or it was a bit warmer, or they had a compressor stall on #2... just about anything.

    How do you compute accelerate stop distance in Spanish?

    Says 'takeoff' in the OP and 2-3 times in the YouTubes...



    Ingested metal fencing into engines?

    Wonder if the gear was damaged and caused a hydraulic leak.

    It seems to me that at least 3 different people were filming this and a rather large crowd was waiting for it. Why?

    The answer is in at least two posts above. This flight was notorious for passing very, very low over the fence and road. It was a local spectacle, and people liked to come see it. For example:

    Just a suggestion, try and read the posts in a thread, especially a short one like this, before posting.

    From what I can detect. The horizontal stab was in full nose up trim as well the elevator, the flaps looked to be in take off setting but the airplane was not able to respond. To me that indicates an over-load. If the number 2 engine experienced a compressor stall I think it would have been recorded in the video. So, they either didn't have enough power or had too much of a load.

    I used to park (with many, many others) at the end of the runway at Denver's old Stapleton airport and watch planes land/TO... there was a road around the end of the runway fence just like that one.

    I watched it again now that I have made it to the hotel for the day. Something inside doesn't look right. That plane does not want to lift. Even when it overruns the strip it looks like it goes straight over the road lifting shortly after.

    Curious as to what the team finds regarding this incident.

    Could you believe that person was alive on the ground at the crash site? Was that a crew member? About 3:50 in the video.

    That's what I was saying, the lift did not exceed the weight. Therefore it remained ground-bound until it gained a little more speed.It's going to stay on the ground until the speed and lift is at the point to get it off the ground. Like previous posts pointed out, could have been an engine problem like compressor stall, flame-out, too heavy a load, and /or improper load balance. The airplane appeared to have all the controls in the proper settings but on any jet with everything dirty, it takes a lot of power to make it all work and if you have got it too heavy or the weight is in the wrong place, it ain't gonna fly.

    Yeah, you could tell that airplane was barely flying. Throw in that sharp turn trying to get back to the airport (around 1:00 into the video), and they didn't stand a chance. I'm surprised it came around as far as it did before they went down.

    Can't imagine what happens to a security fence topped with barbed wire when a large jet goes through it. Some of those people are very lucky on the ground.

    Thank you...that worked (got a 'Forbidden' note before.)


    Flap on the R side was ripped off. Would that result in a hydraulic leak?

    Looks like they got the gear up.

    The flaps and slats are driven by a torque tube that runs along the rear spar with differential gear boxes to run the " endless ballbearing" screws that operate the flaps.

    I think, given the amount of time they were airborne, that a hydraulic leak was the least of their problems.
