Fascinating place. For a moment I thought the half aircraft was a propeller trainer, facing west and lacking its tailplane. But I guess it's a half T-33 alright. I'd say it's a wreck though and not undergoing an engine change.
Between the two T-33s and the third one on the roadside is a preserved aircraft, nose-up on a pole. I guess it's a T-33 as well, it certainly has tip tanks.
