DC-10-30, well no wonder....even more critical with a full boat. I was thinking that AMS-SEA wasn't that much of a stretch for a PW -400, even in winter. 13 hours-ish? I guess their 10's aren't CAT3b (like the MD-80?), or perhaps the recent west coast storms were at play here.
Good job by the folks at Moses Lake...
BEags - ah, I get you now, cheers.
