MiG 15 and BAC Jet Provost at Portland Hillsboro Airport

my guess is a Hunting Jet Provost --- RAF trainer of 1960s

I think the unknown fighter is not a US variant, but a Soko G-2A Galeb, the first Yugoslavian jet design to enter production.

The second plane is a Jet Provost. A friend of mine is part of the group of pilots that restored/owns those two aircraft and they have a MiG-15 and a Jet Provost and are looking at getting other jet warbirds as well. I'm quite certain of this as I've seen pics of both aircraft he took.

Thanks for the inside info! I'll update the map title with the new information.

I showed my friend this map and he told me that it's very likely that he's the one sitting in the cockpit of the Jet Provost in that shot as they were testing its engines. There is a ground power unit hooked up to the jet that you can see in that shot that they used to test the systems after they'd restored it.
