The launch was a bit eventful due to stronger winds than expected (see below); U3B25 went skiing, dragged along the snow by the wind after a downdraft. Nevertheless evidently survived, and climbed to a little over 11,000m as it headed East towards the Atlantic.

the launch was problematic huge gusts of wind and down drafts ... the balloons were being blown sideways and there was no let up in the high gusts of wind. I ran downwind with the transmitter in hand and let go as the balloons seemed to gain altitude. The balloons lowered and dragged the transmitter across the snow before finally getting some altitude... It was terrible abuse for the fragile solar cells and the balloons that normally do not get buffeted around like that. Next time I will be more intelligent and wait for confirmed wind speed ... the forecast was 3knots but it was more like 15kn.
