Anybody catch the footage of the cargo plane crash shortly after take-off at Bagram air base in Afghanistan? Dramatic plane crash caught on camera - World - NZ Herald News Aircraft seems to stall shorty after take-off, wing over and crash. I don't know what the take-off procedures are for civilian cargo but most military aircraft climb rapidly after take-off to minimise the change of small arms fire from the ground hitting the aircraft. Aircraft had 5 vehicles aboard, I wonder if the cargo moved, causing the planes centre of gravity to move rearward causing the nose to pitch up and stall the aircraft?
I'm no formal pilot but love love love microsoft flight simulator; altering weight distribution does affect plane performance and fly-ability. I dare say the load shifted greatly, leading to a tail-heavy stall, and it flopped over.....747s are not the most nimble of things, is hard to get it to stall actually....something dramatic happened....
We used to do stuff like that for fun, although in gliders and Cessna 152 aerobats which are rated for that sort of stuff. Many years ago, I was having an off day, just after take off I turned the trim wheel the wrong way and it was amazing how much pressure was required on the control column to prevent the aircraft from wanting to pitch nose up, the thing just wanted to climb. damn that woke me up, got the heart going till I figured out what I had done.
I wish i didn't watch that. I'm about to head into northern Brazil for a site visit and it involves lots of flights and a milk run type of thing in a Cessna. Just about everytime I head off on a trip that involves small planes something like this happens haha.
They apparently attempt to exceed the V2+10 (15 degree take off) due to the risk of being shot at as immortality stated. It would be easy to stall when you're leaving the tarmac at 155-160 knots with over 400 tonne of weight, especially if a few tonne moved suddenly and violently to the rear. He still had full take off slats and landing gear out adding to the drag (as you would expect, helps with lift, but an Achilles heel in this situation). The pilot may also have simply over-cooked the ascent given I reckon you'd be lucky to hit 11 degrees in a fully loaded 747-400. I'll be interested to see what comes out of the investigation. Awful thing to happen.
yup, weight can have a large effect on how a plane takes off. what they have said so far (or what ive read) is that the load shifted around while taking off. not a good thing as to what happened. yes it is possible to bring a plane out of a stall, but at that height, near on impossible. you basically have to either a) create more thrust then drag (think how a jet fighter flies, as those planes via physics shouldn't fly) b) nose down and have the wings create enough lift to stop the stall also large plans can take off on some very steep angles, although it I don't know how often it is used anymore, but in the old wars and until a few years ago the blue angels used to show off the JATO takeoffs, using jets to create a lot of thrust so you can climb fast. could have, been the weather aswell, (as has been reported). in reality could have been a whole range of different issues (engine failure for example). will be interesting what they find though.
Last time I was in a tiny plane was when I went to Tanna in Vanuatu. It was just over an hour and about 15 minutes in the pilot (a young Aussie bloke about 21) was resting his head on the window and looked to be typing a message on his phone and also looked like he was going to have a snooze. I soon got over my fear of small planes lol.
your not so far from the truth. i'll be waiting for the episode of air crash investigation... tell you what, ive been on a couple of those 747-400's, if one of those crashed in from of my car like in that video id crap my pants... those things are massive. (over 6 million catalogued parts to make one)
that explosion was small too, don't forget that that 747 was only loaded with enough fuel for a short flight from Afghanistan to Dubai. Imagine a 747 leaving Sydney for Dubai with 81000kg of fuel onboard. Makes you appreciate Aircraft technicians ;P
Don't forget that generally speaking the aircraft is required to carry enough fuel to be able to divert to an alternate destination + a minimum 30 minute reserve on top of that.
With a transit only to Dubai, I doubt the aircraft had much fuel on board, especially as fuel uptake in an operational zone would be minimised at all times. These aircraft also generally have a maximum zero fuel weight as well as a maximum all up weight. In the case of the B747, ZFW normally sits around 300,000 pounds below MAUW in the -200 and -300 (which I think this aircraft was). Thus this aircraft would have almost certainly been well below MAUW at the time of the incident. My uneducated guess is that something went wrong on take off. The gear should have been retracted or at least be retracting well before loss of control. The goal of a steep climb out angle in an operational zone requires lift devices to remain active for longer than normal, but for drag from the landing gear to be removed as soon as possible. Maybe the crew were distracted from selecting gear up by some distraction (maybe other emergency), or even lost their after take off routine due the unusual, non-standard climb out procedures. If they adopted the maximum climb out attitude for their particular AUW but with extra drag from the landing gear, the indicated air speed would reduce to below where it should be. And a maximum climb out angle departure is pretty close to the edge of the flight envelope to start with. I noticed that the aircraft started turning left before loss of control, followed by an apparent significant slowing of relative motion then loss of control. Maybe performance at this time was very marginal, and the commencement of the left turn just pushed the aircraft outside the flight envelope. Those who have flown these types of aircraft understand how important angle of bank is at low speeds. Time will tell. And it is a distressing sight for me too. I have lost quite a few friends over the years in aircraft accidents, including ten in loss of control close to the ground accidents.
You mean two parts? (airliners actually carry two black boxes - the cockpit voice recorder, and the flight data recorder)
Very strange crash this. Absolutely no ground fire.....ABSOLUTELY not. Aircraft it seems landed at Bagram to re-fuel with load on board........So had been flying previously to Bagram without any problem/s. Out of Bagram and major incident. Load shift??????? Doubtful. As said time should or will tell.
Bagram seems like a very odd place for a fuel stop. Nobody ever said there was any ground fire, were simply saying that at a place like Bagram which could easily be considered a hot zone where ground fire is a real possibility aircraft climb out at their maximum climb rate to reduce the risk of ground fire effecting the aircraft.
