The Me 262 was the best fighter even it was built and redisigned a lot of times during its competition against the He-280. The -178 was the first jet plane to fly, and it made it 1 day before Germany invaded Poland. The He-280 was one of the most promising designs of the Luftwaffe, it included the first launchable sit and the 3rd wheel of the gear was in the nose and not in the tail, the engine of this plane was designed by Ohan and could reach the speed of 758 k/h but needed a lot of fuel and could only fly a 3rd of time than the Me 262, the 280 could solve this problem with bigger engines but this meant more fuel
