eagl, the lead designer on the Boeing JSF had actually been the the lead guy in Charge of the MD JSF project. When Boeing got Bought by MD the previously MD but now Boeing managers put the MD guy in charge of the JSF design. This pissed off the Boeing lead designer who went to Lockheed and was instrumental in designing the Lockheed JSF.

So I am told.......

Plus I was just referring to the Commercial Business. The 707 is the grandfather of modern commercial aviation, including Airbus.

Why is it always the most fervent gun-loving neo-cons who repeat this mantra? What I want to know is how do you go about booking a flight with a guarantee that the aircraft will be a Boeing, when the major US airlines like American and United (plus a lot of the smaller ones) also operate Airbus, and even McDonnell Douglas? The MD80 is the backbone of AA, so would be pretty hard to avoid.

Its very easy, every flight has an aircraft type associated with it when booking a flight. I take the flight with a Boeing aircraft. why? Because I trust my brother-inlaws judgement as a certified FAA airframe inspector who's been "inside" both makes of aircraft from an inspectors point of view, and a mechanics point of view. To distill his comments, he said "Airbus uses alot of glue where Boeing uses rivets". He won't fly them, neither will I.

I would think that the 787's extensive use of composites (which will require an extensive use of bonding agents rather than rivets for key assemblies) will keep you off that model?

Bonding technology has come a long way. Used within parameters it is a good way to go.

Errrr.... some of the most valued sportscars and limousines are using aluminium structures which are glued together and not welded or riveted.

It's just modern way to make stronger structures instead of using technics from thirties.

That could just as easily be said about the Dh Comet, but yeah, all modern large airliners look like modified 707s with turbofans. They all look like enlarged 262s also...somehow this will become a thread about how 190s are better/worse than Spitfires, I'm sure of it

I rode on an NWA (Who got the bright idea to put a big NWA on the side of Northwest's airplanes anyway? N***as with Attitude they must be) Airbus 319. The only two thing I can say I really liked about the experience was the woman sitting next to me and the A/C system. I wouldn't have ever been on this trip since it was for an interview with a MSP based airline and I had a nonrev ticket that I couldn't exchange. It was August and I was wearing a suit after jumping through the hoops all morning at the interview so I was a good bit toasty. Thanks for making a good A/C System.

I didn't have a view out the wing to verify what might have been what but there were several motors that were excessively loud in the cabin. One for flaps, the landing gear and one more I couldn't figure out what the heck it ws. A guess would've been elevator trim but I don't know for sure. It came on in a longer spurt and then a couple short ones at the end like you might if you were fine tuning for takeoff setting. Didn't hear it in flight or really pay attention since the woman mentioned above actually provided good conversation.

Not to sure I want to spend all the time explaining how many things are wrong with your assumptions, but I will share with you this one fact, the Airbus 319 doesnt have flight control trim systems.

I have extensive experience with Boeing and Airbus, and I fly either.

Did you not read the part you quoted where I said...and I re-quote...

It's still not an assumption that the motors were loud. It's a fact. Since you're our resident Airbus expert...what was it then? Wasn't flaps heard those go down. Wasn't landing gear since we were on the ground.

Yep, that noise is present in every Airbus I've flown. It definitely comes from the belly. I'm assuming something to do with the undercarriage or the cargo bay, but I'm not sure.

You were hearing a hydraulic pump.

Probably hearing the yellow system electric hydraulic pump, it runs when cargo doors are opened or closed. Makes a high pitch whine.

Flaps are normally driven with hydraulic pressure from the engine driven pumps.

Ive flown B767 then moved to A320 from there to the B737NG, and now back to A320.

From my pov, airbus are like porche, great to work in quiet and comfortable, The Boeings like tractors, ugly strong and sturdy.I was never so disappointed to move to the New Generation, exactly like the -200 I flew briefly 8 years ago. I was glad to get back on the A320/319. So thats my background.

Now All I can say is when things go wrong I prefer boeings simple logic and systems. But for the other 99% of the time, Airbus. As to the above episode, eh gad, I haven't heard about it and shall look it up.

Basicaly airbus have 7 computers with the various back ups and millions lines of code probably just need to be re racked (re booted). What alarms me is the typical airline attitude "it works now"and kept the plane flying for another 6 days before the CAA took it off line.

Airbus or Boeing.. if its maintained as it should be, they will go on forever.

I think that's the whole point; too bad some morons aren't able to understand that.

If you want to hear excessively loud electrical motors try flying in a 767, and look at the other passengers faces when the flaps are lowered.

Thanks Dago, I was guessing something like that. Still, it's not the pitch but the irregular tempo of the noise that makes it so noticeable.
