2025

The third and final day of the 2025 Indoor Free Flight Nats saw a change in the outside weather. The morning was a bit cooler and a light rain had settled in. Opinions were mixed around the dome as to how the change in conditions would impact the buoyancy of the air and drift patterns inside the building.

The morning of the second day of the 2025 Indoor Free Flight Nats competition featured several popular events. Limited Pennyplane saw the largest participation of any of the events so far, with 16 entries.

The first day of the 2025 Indoor Free Flight Nats opened with glider events being flown from 8am to 11am. There was a flurry of activity during the three hour window that left Joshua Finn on top of Hand-Launched Glider and Don Slusarczyk in a close second.

The 2025 Indoor Free Flight Nats return to the East Tennessee State University’s (ETSU) Mini-Dome in Johnson City, Tennessee. Tony Italiano brought the Nats to ETSU in 1987. The venue’s stable air and relative proximity to much of the United States’ indoor flying population led to its popularity as a Nats site.
