Lipstick On A Pig, Part Deux.

From the Flight Global article:

"As these engines would be larger than the current CF6 engines, the 767X would require a modified landing gear, to give greater clearance below the plane."

Why not just move the engines further forward and abov... Nevermind.

Too soon?......

No I'm just impressed that Boeing learned something.

I would say the significant difference is it wouldn’t have to fly 160+ kt finals or have artificially high Vr speeds to avoid tail-strikes.

The 767-400 mentioned has very tall gear (airplane appears to be about 1-degree nose-down when parked). It probably gives the clearance they are looking for, to avoid the Max debacle.

I’ve read the estimated development costs for a 797 and they were huge. With their butt currently wedged in the porta-john, Boeing might be cash-strapped and risk-averse to a totally new design.

I’d say this might happen, and would likely be a good product.

I’m down with it just as long as they stick with current nomenclature and call it the 767 MAX

Ha. Solid bet

If you compare a 767 to a 787, what percentage of the fuel efficiency gains is a result of the engine's compared to the aerodynamics and advanced wing design?

And to add to that, wouldn't a 767MAX just a worse version of a 787? How could that be a success?

With all the financial damage Boeing has done to their customers, 787-8’s should be dished out as massive discount to make them that much more competitive vs bringing back an ancient design like the 767. A 767-400 isn’t much smaller than a 787-8 so you’re question is indeed valid.
