I went to the McMinnville Evergreen Aviation Museum last summer. That would be where they house the Hughes H-4 Hercules, also known as the Spruce Goose.
That airplane is so big, I couldn't take a picture of it in its entirety. So here, for your enjoyment, are some pictures of other aircraft, with parts of the Spruce Goose in the background:
MiG 17. One of the Spruce Goose's floats is in the background.
F105 Thunderchief Plus 3 of the Goose's 4 right side engines.
F100 Supersabre. Plus part of the Goose's wing!
P-38 Lighting.
An F4 Phantom II. And another one of the Goose's floats.
A B-25. Plus part of the Goose's tail.
OV-1 Mohawk.
The tail of the Spruce Goose. Under it is the B25 and the OV-1.
Cockpit and parts of the wing of the Spruce Goose.
(In retrospect, I should have taken pictures of plaques that told you what the hell each plane was, but my SD card was running low of space, so I had to conserve memory space.)
