Range is not a single fixed value. All aircraft have a payload-range-curve that is published in the airport planning document.

Satellites are sensors, a necessary component to solve a problem but not sufficient by itself. They're great for worldwide surveying, gathering data from remote places 24/7.

The 787 and A350 have active damping as standard, and I think the entire Airbus FBW range has maneuver load alleviation, which uses the spoilers to unload the wing during turbulence.

Maybe a twin jet A380? The engine is designed for variants up to 100,000 lbs of thrust. That's comparable to the Trent XWB-97, the GE-9X and the GE-90.

I am not sure it can go on A350 and at least we agree that it can't fit on 787.

When is the last time WN sold anything other than 717s? Resale values still play a role when it comes to financing. If the customer - WN - goes belly up, the creditor is stuck with these assets.

What does WN see in the -7 that the rest of the world misses? Especially among other LCC's, the -8 and its -200 variant seem to be far more popular.

Well, if you really need tankers at unprepared airfields you can use converted tactical airlifters like the C-130. See for example https://en.wikipedia.org/wiki/Operation_Eagle_Claw
Same for VIP transport, though VIP's very rarely have the need to visit such locations.

One example did come to mind where both engines were swapped: The A319NEO prototype was first flown and certified with CFM LEAP engines, and later fitted with PW1000G engines to certify that configuration.
No, it is generally required that all engines be of the same model and thrust rating, unless the aircraft is specifically certified for a certain combination.
