Saturday at SD Texas I had a partial canopy collapse then reinflated quickly. I flew through a dust devil. One of the guys that was behind me had a full collapse and fell for a little bit then his canopy reinflated long enough for him to land. Needless to say I was feeling pretty nervous. I didnt notice the dust devil till I was in it. Always keep an eye out for swirling dust and debris and avoid landing anywhere near them.
