What will its top speed be? 264 mph is a bit pokey as jets go.

The company says the jets will be much quieter, more fuel efficient and have lower emissions than current 747-400 models. Quitter, more fuel efficient, lower emission? What the difference does it make? Boeing don't manufacture jet engines. It's the G.E. and Pratt&Whitney or Rolls Royce... BS!

264 was just the test flight. I imagine that it will top out at about 550 mph.

Maybe it isn’t as simple as jack up plane, put in new green engine? I’d think the cockpit has to be made to match.

I believe it will cruise at Mach .86 or a little faster. The cruise for a -400 was in the .84 to .86 range.

Strapping a loaded pallet on the back of a carrier pigeon just won’t work, no matter what Algore says.

What are the main differences in addition to the fuel, quieter?

It has a longer fuselage surpassing the Airbus A340. It is also the heaviest aircraft, commercial or military, manufactured in the United States. On the passenger version of the plane,the 747-8 will feature a new solid-state light-emitting diode (LED) lighting system, which can create moods lighting.This new LED technology provides lower maintenance costs.

Ahhhh. Thanks.
Any news on not having to have a shoehorn to get in and out of the economy seats?

What will its top speed be? 264 mph is a bit pokey as jets go. It's cruise speed is supposed to be Mach 0.86 compared to to the 747-400's cruise at Mach 0.85, or the 747-200 at 0.84. Air Force One, a highly modified 747-200, often flies at Mach 0.92+.
To: Rembrandt
Especially if it is an LD-7 or LD-3!
To: sonofstrangelove; Quix
This new LED technology provides lower maintenance costs. It should help increase range by decreasing the electricity needed to run the lights.
To: Paleo Conservative
~660 mph, that’s considerably zippier.

Haven’t they been using fluorescents already for decades? This is efficiency competitive with LED and much cheaper, though not as long lived.

But aren’t fluorescents bulkier and heavier? It’s not just how efficient they are, it also matters how much they weigh. Fluorescents also have a rather unnatural an unflattering discontinuous spectrum that tends to be greenish. LED’s can be made to look more like daylight.
