Helicopter is up again, Boeing 777X ready for taxi-ing after push-back. Engines being started up.

...aircraft is now at the same holding position as yesterday,
she may turn onto runway 34 at about 19.00 hrs CET Europe.

Saw it live and saw it afterwards a few times again, nice aircraft btw.
But it has a strange take off position, probably it has something to do with length and avoiding a tailstrike.
When you look close, the rightmaingear (first row of wheels) is already of the ground and then the nosegear. Just looking strange to me.

the B787-10 has the same feature. It is indeed meant to avoid tailstrikes.

Lucas probably wanted to refer to the semi-levered gear design on the main gears. An SLG basically has an additional hydraulic strut connecting the forward part of the main gear bogie and the vertical main gear strut. During takeoff this hydraulic strut locks the main gear bogie perpendicularly to the vertical main gear strut, hereby changing the rotation point from the center of the main gear bogie to the aft wheels of the bogie. This results in an increased tailstrike clearance for same pitch (or increased pitch allowance for same tailstrike clearance), hereby improving the takeoff performance.

Technically speaking an SLG is not a tailstrike protection system. The protection comes from the FBW control laws. On the 787, SLG is effectively only available on the B78X. Furthermore it's available on the B77W and most likely on the new B779 (and B778?) as well.

That being said, me too thinks the 'strange' takeoff movement is mostly caused by the light aircraft mass (and possibly increased rotation speed to be on the safe side energy wise, certainly on the very first flight?).

This guy has an interest in semi-levered gears and made some nice close up pictures

but here his comment is wrong, as mentioned in a reply tweet: it's like standing on your heels

Lufthansa is considering converting early delivery slots of some of the 20 B777-9 on order for some additional B777F. Coronavirus made freight more popular than passengers!

Boeing says that the B777/777X combined production rate will be reduced to only 3 per month in 2021. That sounds almost like a death notice for the 777X...

From 5 (current combined rate) to 3 is bad, but a death notice is a bit extreme...
The classic 777 is running on it's last legs in production and the 777X doesn't have a huge backlog yet with a lot of airlines looking to push back deliveries due to the current crisis. It will be one of the largest aircraft in serial production, with global demand generally not expected to fully recover earlier than 2022/2023, airlines are not looking forward to such an expensive huge widebody on very short term.

Boeing has no other choice than slowing production to bridge this gap and hope for recovery in 2023 and beyond (which also gets closer to the time that more of the current 77W users will be looking for replacements). Imo that's not a death notice but common sense.

Boeing says the B777X is being certified as part of the existing B777 family, and not all-new type.

[KriVa]

They have a great track record of doing that, of course.

[sn26567]

Lufthansa (launch carrier) continues to expect the first B777X sometime in 2021. The carrier ordered 20 firm, with 14 options.

[sn26567]

Boeing is preparing to delay its all-new B777X by several months or up to a year, as the crisis exacerbates a drop in demand for the industry’s largest jetliners.

[sn26567]

Qatar Airways plans to take all 60 B777X on order, with first delivering in 2022 and stretched out through to 2029.
