EOSS Flight 360 was launched from Deer Trail CO  May 18, 2024 at 7:07 am reaching an altitude of over 101,000ft.

 

The students (in over 20 cars) meet in Lindon CO to await landing information.  The arrival in Lindon was shortly after burst; however we followed the decent and as the parachute and payloads came closer we scanned the sky and finally saw them floating over highway 36.

 

It was a difficult retrieval, so the EOSS team brought the payloads to the students in Lindon.
