    Before it was lifted onto the bogey’s, it looked to me like there was indeed a slight bend in the fuse.

    no comment……………..

    That would be an aeroplane with all its paint off and showing a bit too much of the undercarriage?

    Old post dragged up….

    Honda Motor Co. may start selling its Hondajet in three years at the earliest.

    Honda Motor May Begin Selling Aircraft in Three Years

    Well, it’s off and running (Has been for some time).
    Any of you Biz jet pilots like the look of this?
    Do you think it will sell well?

    Looking at the picture of MM on the move, there is a bite out of the Stbd elevator, must have been the Stbd main Undercarriage…nothing else came off the Stbd side did it? Engine Cowl doors possibly.
    We only build them to withstand an 8lb bird strike but it stood fast with a 500lb chunk of alloy with some of Dunlops finest on the end.

    According to what I read in Flight, the landing gear on the approach was lowered quite late.

    Raising the gear would have done a disservice – the doors of the landing gear bays would have come down to raise the gear – increasing the drag, and the gear did a pretty good job of absorbing quite a lot of the impact force of the aircraft hitting the deck. No landing gear and the fuselage would have had to have absorbed all of the force, probably doing a lot more damage to everyone inside.

    Correct, before breaking off, the gear would have absorbed a lot of the impact.
    Also, if the gear was up, the drag would reduce and potentially increase glideability, but unfortunately at increased speed. The could have made runway, but at a few more knots and a belly landing – metal meeting concrete.

    Oh, and as there apparently was fuel on board, concrete/metal = sparks. Not good. In many ways, luck was shining down on that crew and pax.

    This is not my area, but elsewhere others have noted FR Doc 03-1816 (below) that deals with a known problem of engine icing on the Trent 800. Seems that the engine deicing system is required to be manually switched on as the automatic activation system doesn’t always work. The problem caused a engine surge and automatic shutdown as ice was ingested into the engine. It was pretty warm last Thursday, so the icing level was high, but we know BA38 was on time, so might have descended straight from altitude to the approach.

    http://a257.g.akamaitech.net/7/257/2422/14mar20010800/edocket.access.gpo.gov/2003/03-1816.htm

    Once below 10k feet, the ice would not really start to build. The anti-ice must have been on for the flight, or other serious consequences would have transpired. The inlet lipskin would have been hot until after touchdown, even if it was switched off at 10k feet.
    Dunno if that kind of engine lipskin has the Goodrich swirl system or a common spray ring. It may even have the electric anti-ice but I don’t think that was in service when this engine was designed.
    However, nothing is dismissed.

    Have you read the other conspiracy theory?…..that the PM’s cavalcade was under it on finals, and the anti-bomb / jamming software in the PM’s car somehow wiped out all signals on the B777. Hmm, double decker bus found on moon springs to mind! But the science is faintly plausible, maybe.
    One thing I did learn today, when it comes to scavaging from a wreck for re-usable parts…….Pax seats are a class 1 structural item and must withstand 16g before they rip out of the rails. So, if saving the seats for spares was a thought, that’s a lot of cost!

    Primary structure of the gear yes, held in place by sheering bolts.
    Not a structural component that will affect airworthiness, AFIAK

    The pictures from Airliners.net were all of over-runs or skids.
    Our B777 bounced at higher than wanted speed onto the grass. The photographs from the rear look like there is a very slight bend in the fuse, indicating a lot of fuse stringers bent. The RH undercarriage went walkies whilst the left just pierced up through the overwing panels. In both cases (Of U/c) the rear spars have now probably got a twist in them and as such are not repairable without a complete wing strip. Costly.
    The shear pins in the landing gear are there to allow the gear to snap backwards when the A/c is in fwd motion, it looks like these were pushed up at impact, wrecking most of the heavy parts in the “Bermuda triangle” (The area between Rear spar and rear false spar. There are a lot of heavey engineered parts in there (Pintle, sidestays, main beam etc.), which require alignment in the assembly jig back at Boeing.
    Obviously both engines are not in good health either but they are an LRU anyway. If the engines met the ground with force, then the Front spars will have a twist in them too.
    If this one is mended, I’m never flying on it.

    From the moment the aircraft gets airborne the arrival fuel is being monitored and pre-calculated (to confirm the pre-flight planning figures). This is then rechecked (minimum hourly) throughout the entire remainder of the flight. It could then be compromised by excessive holding but would still be watched by the crew who would then have procedures to follow to instigate diversion or PAN calls at a much earlier stage. Unlikely (unless either the crew ignored procedures or the bottom of the tanks contained massive amounts of water).

    However, Pilots have got previous for overriding the engineers advice on fuel burn. Trying to get the bird home on time. Remember the Concorde inbound LHR from NY? Eng. wanted divert to Shannon. No says pilot, a boxful of important people need to be in London by mid morning, he wasn’t for putting them in Ireland. Landed at LHR with 4 mins fuel left. Hardly enough to get to the apron. Pilot was sacked. He was the favourite pilot too, his mugshot was on all hte billboards for the Concorde.
    No fire, the engines were flat spotted by the scrape. No fuel, that’s why.
    Just my opinion.

    Just for the record, by the way, those bottles in the photo arn’t all from tonight although the bottle in the middle is being merrily consumed right now and shall be empty in a couple of hours. 😀

    As for the way people drink (and fail), I couldn’t agree more. There’s nothing wrong with drinking a shed load as long as people are sensible, and that seems to be the key thing that’s missing. Drink yourself stupid if you want, but know when to stop before things go wrong!

    Oh the photograph confused me, I didn’t realise it was a 3 gallon bottle 🙂

    How dumb is that!

    Not only to launch it, but to sell it in the 1st place. Have you seen some of those “Toy” rockets available in the states? 1,200 feet altitude is possible. Probably more, it was yr2000 when I was last in a US toyshop.

    But it’s the Daily Mail.
    So, as per any of their splashes, it’s either (a) Wrong (b) Knee jerk/over reaction (c) unimportant and trivial.

    The truth is more likely that people are attending the hospitals more often. Todays youth don’t drink any more than when I was 18. In fact maybe less, because I think we had more beer tokens on a like for like basis.
    Of course we had fights etc. but never knives and guns. We didn’t end up in stupers so bad that we were incapable of speaking.
    So, it must be a combination of drugs and alcohol. I also believe that with the decline of the working environment (99% of us polish our backsides on a chair in an AirCon office these days) there seems to be a propensity to get ill / drunk far easier than say the 70’s. No immunity.
    Also, if we got ratar5ed in the pub, the old guys would give us a clip on the ear and send us home. And we’d generally respect that.

    We all like to drink our own body weight in booze, I still do now and then but todays drinkers seem to fail the basic rules, don’t mix the grape and the grain etc.
    Today, the routine seems to be: –
    (1) a shedfull of cheap beer in Wetherspoons.
    (2) a further shedful of beer in several better pubs/bars that cater for the yoof. Wine by the bottle too.
    (3) into the club, a shedful of alcopops and other spirit based cocktails.
    (4) vomit.
