Sunset on HASP

HASP has been flying for over 12 hours and, so far, has about 10 1/2 hours at float. This flight promises to be a long one as we are in "turn around" conditions. However, the indeterminate winds can also be a problem. Up to about a 1/2 hour ago HASP was on a southwest track and heading straight for the White Sands Testing Ground. This is restricted airspace that is close to the U.S. border with Mexico. As we can not let the balloon cross into Mexico and the chase aircraft would not be allowed into restricted airspace we would need to terminate the flight in a few hours. Currently we are on a southeast to south track which is much better as it avoid the White Sands area.
