Hello Guys! I'm sort of new to KSPI, and I'm having a problem that I don't know if is a bug on the version, bug on my installation or is intended. I'm trying to start a Thermal Turbojet (atmospheric or air intake fuel mode) engine at EVE on a 70km circular orbit ( barelly at the end on the EVE atmosphere ) an it explode instantly. Is this right? If so, Why? I understand that these kind of engines overheat a lot at high speed but I have 2 pre-coolers attached directly to my only intakes reporting active status an no oxygen( as expected from Eve), shouldn't this at least don't create a instant explosion? And I don't understand the explosion at all, the basic work of these engines are to overheat the air at VERY high temperatures and then exaust it? High speed should mean small times to heat the air and then have almost zero thrust? I think these kind of engines should overheat at slow speeds because the air would be very hot, making us use the least throttle possible ( configuring the throttle limit to low values to take off ) Edit: It seems to be a bug where the engines explodes if there is not enough fuel (air) since I started a engine later deeper into atmosphere and it worked
