Are there any resources for drawing real life aircraft, military in particular, traditionally? I'm a beg and aviation autist but I seriously struggle with drawing jets right. I can do just about everything good enough to a point where I'm satisfied with the result but my jets come out as incoherent messes. Even the slightest misalignment makes it unrecognisable.

Is the easiest way to just get a 3D model and trace/copy from it until I brute force myself into learning to do it freehand? I'm only asking because I'm very particular about my jets and want them to be recognisable down to the very variant. I'm genuienly dumbfounded how the Area 88 animators drew the in motion so accurately, especially when references for such things were incredibly hard to come by back in 1985 (and a lot of it was still classified even).
