On Tues, 9/28, Blackswift operated their UAV from about 9:45 to 10:15.  At the end of this, Bill (and I) launched a sonde.  After everyone left, I (and Terry!) lowered the tower (10:40–11:00).

The UAV flew one repetition of a "square wave" pattern, with long legs N-S at altitude of 27, 67, and 107m AGL, with 0 AGL on the ground at the base of our tower.

As far as we know, this is the last of the UAV flights this year.
