The aircarft looks a write off, but at least every survived!:yep: I bet the pilot woun't be buying beers for awhile!:D

Then it came out it was a 777 and I scratched my head for a while after drawing a blank on trying to think of previous incidents involving that. Indeed a very good record it has. Yea, I'd say it looks like a total loss to me. But whatever happened, it sure handled that landing well. That does look like a dangerously high AoA in the video above, too. I guess it's just a lucky model number! :88) Cheers to the pilot. So far it looks like he'll be the hero of the day. |

I'm going to take a stab at it and guess that wind shear struck the 777 in the final moments of it's approach. At lunchtime outside our office the weather was highly changeable in that the wind was at times gusting very strongly before suddenly dropping down in intensity to almost total calm. We also had from no where a sudden burst of rain which was almost like hail. In short the weather was very unsettled. I'm guessing from this that we were on the edge of a weather front around the Heathrow and Hounslow areas between 11am to around 3pm when the weather was extremely unsettled. There are also a couple of very large aircraft maintenance hangers within close proximity to the runway approach and I wonder if this in some way along with the weather conditions contributed to the crash. So I'm giving Boeing and the 777 the benefit of the doubt right now. The next 48 hours should prove interesting with regards to the accident investigation prelim report. :hmm:

weather could have had an impact on the aircraft, but not the extent that it would loose all electrical power...that is a very serious problem indeed! It could just have been some faulty wireing. We will just have to wait for the BAA's report on the crash.

I'm putting it down to HunterICX being given a turn in the pilots seat:lol:

Well there's the crew. Cheers to them again :up:

as was said above, the 777 has a good reputation for technical reliability. And as far as this amateur that i am can say, i prefer the cockpit ergonomy of modern Boeing designs anytime over Airbus. I cannot imagine that we have to think in terms of pilot error regarding this accident. |
Interim accident report seems to blame the fadecs or signalling to them!
Edited for clarification. |

What are the chances of it failing though? Sounds like something really went wrong, assuming there should be enough redundancy in the system. Has there been any incidents on other types of planes with similar FADEC systems? Or would this technically be the first one? :hmm: |
Just think of basic electronic systems for a minute.If you send a bad signal down a wire it will affect all the end users.The signal in this case seems to be an increase thrust signal.The signal will be the same whether it was generated by the auto thrust or manually.It ends up in the same place and will be in the same language.Now imagine that signal is corrupted for some reason.The signal does not get through and thrust will be frozen at its current position.In this case that is idle power.Until that rogue signal is removed nothing is going to get through.
This is the first time this has happened to multiple engines at the same time. Result is a very big glider. |

A new lighting system is to be installed at Heathrow:http://www2.b3ta.com/host/creative/6...510/runway.gif

In certain industries there is a thread of black humour.It makes us feel that after an incident or accident such a thing will never happen to us.I borrowed that image from an air traffic controller thread on PPrune.
