• First launches from Spaceport Cuxhaven - . Nation: Germany.

  Cuxhaven saw its first use as the 'Gateway to Space'. The DRG (German Rocket Society)'s 'Rocket Flight Day' started out with 7 firings of the 'oilspray' rocket to ranges of 100 to 300 m. The terrible weather served to demonstrate their function admirably. This was followed by a launch to 100 to 2000 m altitude of several small model rockets. This was followed by delta-winged rocket built by Koschmieder, which reached 3000 m and was recovered by parachute. Next was a prototype 20 kg meteorological rocket using a new solid propellant developed by Deutsche Dynamit AG. This produced 1500 kgf and reached Mach 1.5. The rocket rose to 4000 m but the recovery parachute deployed early and the meteorological instruments were not recovered. Finally a test of the first of Ernst Mohr's big rockets was planned. The rocket had 50 kg of propellant, produced 5 tonnes thrust, and was to have reached Mach 1.5 at burnout and an altitude of 20,000 m. However the launch was cancelled due to bad weather.

• Mohr Rocket launch attempts - . Nation: Germany.

  First attempt to launch Ernst Morhr's larege meteorological rocket. The rocket had a total mass of 150 kg, consisting of 75 kg propellant, 60 kg structure, and 15 kg payload. The motor produced 7800 kgf for 2 seconds. The rocket was 30 cm in diameter, 1.7 m long, and had a payload dart 56 mm in diameter and 1.25 m long. Three attempts were made to launch. Two hung up on the launcher, and the third was unstable after launch and crashed near the launcher.

• Mohr Rocket reaches 50 km altitude - . Nation: Germany.

  Three launches were made from Arensch, including two successful launches of the prototype of the large meteorological rocket developed by Ernst Mohr of Wuppertall. The launches were witnessed by Vice-President Ross. The redesigned Mohr rockets were 2.5 m long, 30 cm in diameter, had a total mass of 80 kg and produced 7.8 tonnes thrust. Cutoff velocity was 1200 m/s at 1200 m altitude. The payload dart then separated and coasted up to 50 km altitude. It was later planned to install meteorological instruments on these rockets.
