My main curiosity is that in other images of the 262 and other early jet aircraft you can see the exhaust come out of the engines. You know... the fire cone flowing out of the engine . I have seen this happen in modern day jet aircraft but not the early ones ( 1940-1965 ) . Also what's up with the fire exhaust anyway ? Sometime's it looks orange like or sometimes even blue ! Which shows that the jet exhaust is very hot but I thought that jet engines are simply fuel powered turbines that control the airflow or jet stream from the air intake allowing greater speeds then a piston engine. I would also like somebody to clear up the main workings of a jet engine as well since I have always been a little confused on the subject...
