Well done nli2work! More variety, larger or smaller, would be MUCH appreciated in the air breathing engine department, but, this thread specifically pertains to 'large' turbofan engines... or i suppose air breathing, high thrust, high bypass, non rocket engines. I understand they're a niche as they would really only be meant for large spaceplanes demanding high thrust, possibly only on Kerbin. As such, a product like this is probably low priority at this point but if there is a spaceplane specific update / expansion planned, I feel it would make an excellent addition to that. Great feedback though everyone, and all opinions welcome!
