What is that opening that you see on the fuselage of DC-10 in front of the wing below the window line. It looks like a fuel door thats sideways, but of couse is not. Is it some sort of air intake for the APU? Heres a link to a picture with one showing, its right below the G in Varig:

You can take the pup out of Alaska, but you can't take the Alaska out of the pup.

I was curious about that myself, I saw one of World's DC-10Fs parked over by South Cargo @ ATL last week, and noticed that valve and was curious about it.

I promise I won't pull an Artie Lange......

For those who choose not to read the link above, the short answer is that it's part of the pressurization system. The DC-9/MD-80 has a similar valve design, but it's located below the left engine, so it's not as visible.

It's a pressurization dump valve. DC10's arent pressurized on the ground. When the plane lands the dump valve opens to equalize pressurization if the auto/manual system fails to keep the pressurization schedule which should relieve pressure 1000' (?) above field elevation.
