alright sooooo basically I was gonna suggest this earlier but I completely forgot and only now have I decided to make this suggestion because of another similar instant.
essentially this is a system that lets you completely refund aircraft however I believe there must be one basic rule, which is the fact that the aircraft must be fresh and never used, at least under 1 minute of use for it to count as refund eligible, however it does not matter if you spent money on maintenance or paint as none of that would be refunded, again, the aircraft must be never used, even if its 100-99% repaired.
pros: You get to get all UP spent and all WP spent on purchasing the aircraft, this means, if you accidentally buy an aircraft when it suddenly goes out of stock, you can easily refund it.
cons: You will not be able to use the aircraft again, and there is a (X amount of time) refund timer for that aircraft (this is up to you aero gods)
I have provided a simple image of what this could look like
(also if you bought it without up you can only refund for wp)
