Balloon system overview at launch site in Ft. Sumner, NM. Note pickup truck and ground personnel for relative scale. The entire length of the flight system is not depcited but ranges from 150 to 300 m. Photos taken at launch of Long Duration Balloon Technology Flight #651 in August 2014.

Simplified design for a ground chamber test that would simulate a conventional balloon flight profile. Temperature and pressure conditions shown for a 12 h flight launching from Ft. Sumner, NM, in autumn (based on data from Test Flight #667NT).
