the names of the original planes in SimplePlanes are very strange, the WASP is F/A-18 in fact, its nickname should be Hornet, but the name in SP is WASP, although they are almost the same creature, Hornet is the official nickname, not WASP. The pigpen is JAS39 Gripen, but is named pigpen, why?
To avoid copyright, isnt that obvious?
Avoiding copyright or they just want to be creative with the names
