The Bell FM-1 Airacuda
The Airacuda first came out in 1937 and with its high-level design and characteristics, it was expected to be amazing. It was appreciated for being a fighter jet but had many shortcomings like overheating rather quickly. One time a gun fired inside and the entire inside instantly was filled with smoke.
The Vought F7U Cutlass
With its special design, the Cutlass is very well known. It looked very cool but had many issues. It managed to reach high speeds but did not stay in the air long or reach high altitudes. It lacked the strength to fully take over and crashed almost 25% of the time.
