>>"The first purely Vril disc - the Vril 1 Jager (Hunter) was constructed in 1941 and first flew in 1942.
It was 11.5 meters in diameter, had a single pilot, and could achieve 2,900 km/h - 12,000 km/h! It flew with a metal dome at first but subsequent test versions had a heavily reinforced glass dome and could seat two crew. Flight endurance was 5.5 hrs. It was planned to arm this craft with two MK-108 cannon plus 2 MG-17 machineguns. Seventeen of these craft were constructed and tested between 1942-44 with 84 test flights."<<
What is the muzzle velocity of an MG-17 machinegun, out of say a 30 inch barrel? How fast does the velocity drop off to slower than the supposed disc craft.
