HEAT 1X Tycho Brahe during the winter 2010-11. After again experiencing a technical problem with the auto-sequence, the rocket and spacecraft went up in the air. After lift-off, HEAT 1X Tycho Brahe achieved supersonic speed but its flight path deviated from the vertical, so Mission Control had to shut the engine off after 21 seconds. Maximum altitude was estimated to 2.8 km and the ground track was 8.5 km. Booster and spacecraft separated but a parachute was torn off the booster due to excessive air drag.
