As of April 30th, 2024, I have recatalouged and re-numbered aircraft designs from 2019-2023 era with a total of 684 aircraft. (a.k.a. Original 684)

As there is only one research remaining in academics, alright. Suggestion:

Pick a number from 1 to 684 and I'll try to build it. The design would be , a surprise. :)
