3 HD camcorders attached to a helium balloon (horizon, earth and balloon) filmed the ascent of the ensemble to over 31 000 m altitude with temperature measurement , altitude and pressure.
IMPORTANT 1: If the plane touches the probe balloon, it is because it deliberately chose to do so because it appears on the radar screen.
IMPORTANT 2 : All necessary authorizations have been obtained from the french competent authorities. The release date is defined 6 months in advance, with no possibility of modification in case of bad weather. The onboard mass, the dimensions, the flight chain obey to precise standards and the release is realized under the responsibility of a competent person and sworn by the French authorities. A radar reflector allows planes to locate the basket and a parachute is also inserted into the flight chain. The authorities know exactly where and what time the balloon takes off.
