Here is what an MV-22 looks like (I borrowed this photo from Military-Today).
Other sitings recently include a pair of F-18s, a C-130, a C-17, and a P-3, all in the Yakima area. If you are in Washington State and would like to contribute sitings, feel free to leave a comment, I welcome it.
There are certain places where activity is expected, for instance, Whidbey NAS, McChord AFB, and Fairchild AFB, however, recently Fairchild moved many of its assets to Moses Lake, at Grant County International Airport. One would expect C-17s, KC-135s, and EG-18Gs from those places. Portland International hosts ANG F-15s. Other aircraft would likely be transient.
Take, for example, this C-130 that passed over my house tonight. Where the heck is he from and why didn't he fly lower, so I could get a better picture? Here are my pictures.
This is obviously a C-130, but what model? Have a look at the lumps and bumps.
It doesn't seem to have the requisite lumps amidships, though, how about this next one?
So, let's have some comments, folks! Update me!
