I am super stoked for 0.625m jet engines. One of my favorite standard builds requires a pair of them, and I've had to resort to tweakscaling a pair in the past. I use some other mod's shuttle engines, they look just like these new ones and also come in straight and angled variants. I enjoy making planes, often in a separate sandbox save; rarely do I need to build one in Career. Sometimes I'll place a flag at the poles or somesuch. Anyway, I'm glad some part are getting some aesthetic attention. I hope every part gets an art pass before the game is done.
