EOSS-283 was launched from Windsor Colorado on 3/10/2019 with six EOSS beacons.  All payloads were recovered just north of the Colorado state line in Nebraska, near Peetz, Colorado.

This flight was particularlly challenging from the beginning because of multiple postponements due to the weather.  Finally, we had a calm day, no extremely cold weather or snow, and a resonable flight prediction that showed landing in the state of Colorado.
