The Yak was known as the backbone of the Yeager Waffe and was even used up until the 60s due to its capabilities with even the Honorable Chairman the 1st of Yeager stating to a general in his office “This plane is the reason were winning this war General to stop production would be suicide.” The plane was very effective as it had multi-role capability and was simple to mass produce so even today if you were to buy one it wouldn’t be too awful high for a plane. The plane was also known to be a common fear for wright pilots even earning the name of Satan’s Eagle because for one it looked like an eagle and secondly because it would drop gaining immense speed and then would come back up shooting the bottom of wright planes open and typically killing or in less cases severely paralyzing pilots from the wright airforce but this tatic slowly faded out with the invention of guided missles. (So this is my fictional aircraft hope you enjoy also dont pull the stick too far or it’ll jerk repeatedly.)
