At 13:55, the aircraft crossed the clouds; at 14:21, the ozone layer was clearly visible; at 14:42, the ozone layer was clearly visible.

HYPOTHESIS: At the time of the last photo, we were close to the moment of bursting. We think it stopped because the gondola moved and the camera must have hit something and gone out.
