Delta 777 Diversion To SEA

Sun Jun 23, 2013 9:20 pm

Delta 180 from PVG to DTW diverted to SEA today, landed 10 minutes ago, 777-200. DTW weather doesn't look terrible, and this flight doesn't seem to ever have issues with needing a fuel stop, anyone know why? I recall seeing the HKG-DTW flight divert to SEA one day as well last year.

I am not sure, but DL 159 had to return to DTW today when they blew a tire on takeoff. Turned back up around SAW and dumped fuel most of the way back to DTW. Tough day for DL's 777.

Any landing you can walk away from is a good landing! It's a bonus if you can fly the plane again!!

They flew across the pacific awfully low at 31000 before descending to 25000 for over an hour. Something wrong with the plane is what would cause a plane to be low like that
If you have never designed an airplane part before, let the real designers do the work!

Flying low, I'll guess stronger than anticipated headwinds at higher altitude and also lower, so added extra fuel at SEA. Just speculation.....

The plane seems to have been on the ground for about 1:50 and then continued on to DTW. She flew to DTW at 37K so doesn't seem like a pressurization issue.

Maybe strong winds/low-fuel or a medical.
Some see lines, others see between the lines.

Ha, small world...I was on final when they took off and saw the county ops car going down the runway and he just came on and said, "there's debris EVERYwhere...close 22R."

What about adverse winds or bad turbulence at higher altitudes? Anyone know what flights on similar tracks were doing?

If it was a pressurization thing or other mechanical problem, I'd think they wouldn't be flying ETOPs at any altitude, but their track looks like it crossed some relatively remote regions of the Pacific. The map might be distorted, but it looks awfully far south to be anything close to ideal for either Detroit or Seattle.

Why do Aerospace Engineering students have to turn things in on time?

It is not uncommon for flights from Asia to the Midwest or east coast to ride the jet stream and enter the North america continent near the US Canadian border (usually on the US side to avoid Canadian overflight fees).
