Ok guess I am just looking stupid now, thank you everyone for the help.

I am just getting confused, let's see what I'm doing wrong, I take this picture: Offcurse my plane is not climbing but just free fall on axis Y (my plane have angle of 0 let's say) so my plane isn't moving backward ?

isn't drag at certain point be equal to thrust ? If drag is based on the speed, and because there is no speed increase deriving from thrust (my immaginary airplane has no starting speed) we will get that thrust = 0 so what's left is only the negative force of drag that will increase as my plane...

Sorry my drawing skill is very poor, the first plane is the step at time 0, my plane is on starting position with velocity 0 and thrust =0 The second plane is the action after 5 unit of time, my plane went backward and down because of the gravity and the drag as it get velocity but no thrust

An ideal airplane or paperplane, set in space and let it fall down freeely as stated before.

So basically as my beautiful pic show this is correct immagining the plane with initial v0 let it fall without thrust

Ok, my knowledge on physics and vector algebra is quite bad so I am just learning, be patient with me. Based on this image let's say my airplane have a direction of 15° and accelerating, then suddenly stop acceleration and point down nose of the plane, get some velocity and still without...

Yes flaps in case of airplane would be involved indeed, the code I put there is just one example it's not the full code but it simulate well a rock ; (dir) is the variable for the direction I could change, isn't enough for pitch angle ?

I have to admit I am not good on physics but I am willing to try to understand how is possible for a plane or a glide that's falling without thrust applied downward to make a loop (by changing direction or using the elevators on the tail of plane, like in this picture. I am try to write a...
