Mountain View, CA: What's up with that big plane that flies around out of Moffet(?)

General Questions
#1

It’s a big, four-prop military plane that flies low circles over the South Bay. I’ve been seeing it for years. I haven’t seen it take off or land, but it seems to be coming and going from Moffet Field. Any information on it?

#2

Does it look like this?

#3

Do they still fly P-3s out of Moffet? Is it one of the Ames Research Center’s test aircraft?

#4

That looks like it. So it’s an Air National Guard plane. I’m guessing that most of the time I see it fly around it’s for pilot training.

Thanks.

#5

That’s a baby…keep your eyes peeled for the Anatov An-225 that’s been known to drop by there on occasion. http://en.wikipedia.org/wiki/Antonov_An-225
