The Walter engine stalled about 15 seconds after take-off. It is estimated the Natter reached 1,500 m (4,900 ft), at which point it nose-dived and hit the ground with great force about 32 seconds later, some kilometres from the launch site. Unknown at

144-421: The first manned vertical take-off of a rocket. The experienced test pilot was told to execute a half roll if the Natter should veer off course. Initially, the Natter rose vertically but, at an altitude of about 100 to 150 m (330 to 490 ft), it suddenly pitched up into an inverted curve at about 30° to the vertical. At about 500 m (1,600 ft), after the release of the solid fuel rocket boosters,

160-458: The flight, which lasted for 55 seconds and covered a horizontal distance of 7 kilometres (4.3 mi), calculated an average speed of about 800 kilometres per hour (500 mph), thus about 14 kilometres (8.7 mi) were traveled in total. As an experienced test pilot had failed to control the Natter, which was intended to be operated by many inexperienced pilots as an interceptor, the SS cancelled

176-428: The fully closed position at launch. The pilot's headrest had been attached to the underside of the canopy and as the canopy flew off the pilot's head would have snapped back suddenly about 25 cm (9.8 in), hitting the solid wooden rear upper cockpit bulkhead, and either knocking Sieber unconscious or breaking his neck. At the impact site, about 7 kilometres (4.3 mi) away, a 5-metre (16 ft) deep crater

Erich Bachem surmised he had involuntarily pulled back on the control column under the effect of the 3 G acceleration. Examination of the canopy, which fell near the launch site, showed the tip of the latch was bent, suggesting it may not have been in
