And as far as the other exampels it was the first operational fighter with ejection seat since the do335 never got operational.

WELL It turns out that the He 280 had the first like I said and the first to properly use one but it was used OPERATIONALLY the first time on the He219 Uhu night fighter.
Check the dates in these paragraphs etc. I still Win the argument.

The first ejection seats were developed independently during World War II by Heinkel and SAAB. Early models were powered by compressed air and the first aircraft to be fitted with such a system was the Heinkel He 280 prototype jet fighter in 1940. One of the He 280 test pilots, Helmut Schenk, became the first person to escape from a stricken aircraft with an ejection seat on 13 January 1942 after his control surfaces iced up and became inoperable. The fighter, being used in tests of the Argus As 014 impulse jets for Fieseler Fi 103 missile development, had its regular HeS 8A turbojets removed, and was towed aloft from Rechlin, Germany by a pair of Bf 110C tugs in a heavy snow-shower. At 7,875 feet (2,400 m), Schenk found he had no control, jettisoned his towline, and ejected.[2] The He 280, however, never reached production status. Thus, the first operational type to provide ejection seats for the crew was the Heinkel He 219 Uhu night fighter in 1942.

In Sweden a version using compressed air was tested in 1941. A gunpowder ejection seat was developed by Bofors and tested in 1943 for the Saab 21. The first test in the air was on a Saab 17 on 27 February 1944,[3] and the first real use occurred in 29 July 1946 after a mid-air collision between a J 21 and a J 22.[4]

In late 1944, the Heinkel He 162 featured a new type of ejection seat, this time fired by an explosive cartridge. In this system the seat rode on wheels set between two pipes running up the back of the cockpit. When lowered into position, caps at the top of the seat fitted over the pipes to close them. Cartridges, basically identical to shotgun shells, were placed in the bottom of the pipes, facing upward. When fired, the gases would fill the pipes, "popping" the caps off the end, and thereby forcing the seat to ride up the pipes on its wheels and out of the aircraft. By the end of the war, the Do-335 Pfeil and a few prototype aircraft were also fitted with ejection seats.
