The rocket thrusted upwards, You thrust up, you thrust forward.
I guess we can agree to disagree but if the said rocket is traveling horizontally to the earth (ie: our jet aircraft) and you want to go up where do you point the nozzle? UP and pointing the nozzle up is up thrust. This is a topic that we can discuss untill the snakes take the next plane back to Ireland.I would agree with you if we were talking about a tractor propeller but we are talking in you words thrust "reactive force". We can still be friends.By the way I've been to your country (1968) and it was very bueatiful.
