Yep, you’re right, it’s an L-39 Albatros.
Walked over and wound up getting a tour of the TT facilty. Quite a nice operation, especially with the connection to TCC and OSU at the flight center. Has one of the few hyperbaric chambers in the state apparently.
Contents of the hangars were of particular interest to me. Where can I find a crew to hijack that 25 to: airvictorymuseum.org/
Corsair was on ground display but I didn’t see it flying earlier. CAP sponsored fly-in today with static display. Very nice USAF liveried Trojan on display, along with a YAK/Nanchang a YAK 11 and several Texans.
Maybe 10 people walking around in the period of time I was there, very sad. Don’t know if this was an advertised event or not, but there certainly wasn’t any easy way to get to the aircraft, nor any signs with directions.
