I just put everything simply in to the "backforce"
even the air fricition and what so ever are supposed to be within the "back force"
and
if the missing drag u mentioned is the drag force by the engine
JTD have already said Mass*G >> engine thrust or so
"earth gravitational constant >> excess thrust / mass, so excess thrust / mass doesn't really matter."
he is wrong?
