Assume there is a wingless augmented flight pack such as a jetpack attached to a person's body. Assuming that there is sufficient amount of power. will it be possible according to the laws of physics to fly in a horizontal position instead of a vertical position? What are the requirements for someone to be able to fly horizontally using a wingless augmented flight pack? This question ignores irrelevant factors such as health risks and etc. It's just asking if it's possible within the laws of physics to fly horizontally using a wingless flight pack.
