It's actually approaching runway 16R at PAE. The clouds just give an illusion that the plane is at a high altitude. Nice shot though!

Until the Landing Gear is proven during the first series of flights it is typical to be very cautious. The whole aircraft is untested and there is the potential for a lot of different things to go wrong. Therefore potential problems with the landing gear occuring during a critical flight phase and close to the ground are eliminated by raising and lowering them well after take-off and well before landing. Hey, fuel burn is a none issue on first flight; provided you have enough  .

Not in this case since it is first flight but there are also landing gear tests done in flight. i.e. Gear down envelope proving, free fall testing, cabin noise testing, etc

Actually, the weather yesterday and today hasn't been that bad. Skies were clear-er in the later afternoon and today was nearly cloudless in the afternoon.

It got me thinking , how will the pilots deal with the licenses between 747's , like in the case of Lufthansa that will have both models . can a pilot with a ATP license for 747-400 , would be able to fly the 747-8 too ?

Both planes have the same flight decks. So in my opinion there won't be any problems between switching after a short introduction in the differences beyond the flight deck and in flight characteristics.

Same type rating between the -8 and the -400. At one point on the newairplane.com site, there was a graphic that showed the time it would take to transistion between Boeing's new models: 777, 747-8, 787-8. I can't find it now.

Doesn't the 748 share the updated flight deck of the 744ER, with the flight bags of the 777/787? BTW, is anyone else impressed with the wings on the 748? As well as the engines?

No. I think I liked the vertical winglets much, much, much better. It was so distinctive. These new raked wingtips look great on the 777 and 787 but on the 747 I just feel like something's missing since I'm so used to the winglets!

What is the thing training from the back of the tail...? We saw it on the 787 too....some sort of instrument involved in the testing, of course, but what does it do?

True they did look great on the 744, but 3 other models of the 747 were built without winglets, so it's not so weird to see the 747 without winglets. What is weird is the length, wingspan increase, and size of the engines. It's the first time (withholding the 747SP) the 747's dimensions have been changed so drastically, particularly in regards to the wingspan and engines.

It's a trailing static pressure cone. It measures atmospheric pressure in order calibrate and confirm the altitude readings the airplanes avionics are giving.

In other words I believe it just confirms if the airplanes avionics are accurately measuring altitude. A minor detail.

I was disappointed that the first videos didn't show the graceful arch onfthe wing flex like it showed in Boeing's illustrations prior to the flight (and like the 787). I looks like the wing starts to arch, and then around the in-board engines it bends towards the ground.

I heard they weighted in at 600,000 lbs for this flight, which is way shy of the 900,000 + lbs MTW for this type. Maybe at MTW the wings will arch like the illustrations?

Yeah, closer to 1,000,000lbs actually.  Wow! I wonder if the extra 375,000lbs will make the wings bend like the 747-8 illustrations...?

Its called a "trailing cone" it is extend aft of the aircraft into still air for calabration of the pitot static system.

Those engines look to be the right size for a 747...I think with it and the new wing, it's quite pretty.

Ya know, it really is. Maybe it's the extra length of the fuselage and/or wings or the larger engines or the smaller hump or a combination of all of them, but it's pretty magnificent.

I think it's all of the above. It's just one of those timeless pieces of machinery. Boeing really did a bang up job with the increased length, span, and larger engines, and the best part is that all of the increase will translate into better performance. It's a win win for us.
