I'm going to miss it when it's gone. I never get tired of watching the Delta 747-400s flying not too far from me, either.

It's all about being more efficient. They can save that weight and utilize it somewhere else. If they can provide another amenity that means more to passengers or can otherwise contribute to their efficiency, a little sound is an easy sacrifice I'm sure.

It's been a workhorse of cargo airlines for quite a while. I think they'll be in the air for some time to come. But their days as airliners may be coming to a close.

Cargo market has been shite for large aircraft, the 747-8 was supposed to be most successful as a freighter. Conversions of 767s and 757s have dominated the market.

I just showed my coworker (also mech. engineer) the new engine. First thing he said was "dog pecker"

Saw an A-10 making strafing runs at the Barry Goldwater Range in AZ the other day. The sound that Gatling gun makes is incredible.

ETA: I got to see two of them fly when I was at the beach for my senior trip near tyndall AFB, along with plenty of F15's and a few 16s. I spent the entire week jealous as hell of the guys sitting in those seats.


The F16's at Shaw haven't flown much this summer( because of the government.) but when they come in to land they fly right over my house. Getting so low sometimes you can see the bombs and stuff under the aircraft. They've gotten up in the air a lot more recently due to this bull shite about Syria.

Have never seen an F15, but there was an F18 SuperH at the air show here 3 or 4 years ago.

Whoever cropped off the airliners.net logo and the photographer's name (Fyodor Borisov) shouldn't have.

This is the original image

Those chevrons actually have a fuel efficiency penalty. You'll notice that Airbus' latest two jets, the A380 and A350, don't have them. Boeing chose to take the efficiency loss in order to reduce the aircraft's noise signature. The 787 has them as well.

What do you think the price tag is on a brand new Boeing 747-8?

$356.9 million. And that comes pretty stripped down. The customers have to buy the interior and also the engines separately.

Lead time?

I want to say 5-10 years? I know right now the order backlog is around $400 billion and about 5,000 planes (not just 747 though).

I heard an interesting story about those winglets that you see on the planes. So apparently an engineer at Boeing initially had the idea of the winglets, but the Boeing execs weren't buying it and didn't want to invest in it. So this guy left Boeing and started his own company that produced them and sold them back to airplane manufacturers. Once Boeing saw how much they improved the fuel efficiency, they ended up buying the guy's company

Specifically the Aviation Partners Boeing blended winglets seen retrofitted to the 737, 757, and 767. The newest 777s, 747-8, and 787 use a raked wingtip developed by Boeing themselves (AFAIK) which is even more efficient for long haul.



The next generation of 737s (737 MAX) are going to use a scimitar winglet, also developed by APB.



True story: Boeing's first jetliner with winglets was the 747-400 in 1989 and they were done for marketing--they didn't really reduce fuel consumption hardly anything past the additional drag and weight of the winglets themselves.

not true at all, the winglets provide a dramatic increase in fuel efficiency, the first time I flew a 767-300 that had been retrofitted with them was on a leg from HNL-DFW, at that weight, the fuel flow at initial level off would be 17k/lbs./hr on a plane without winglets, with the winglets, the ff was 13k/lbs./hr., fuel is the biggest single expense for airlines, and few would place a billion dollar order for aircraft fitted with anything that would increase ff by a pound an hour for marketing purposes

I just always liked having 4 engines in case some of them broke
