Robert Frost, Quora contributor, Instructor and Flight Controller at NASA, answered the question on Feb 2, 2020, first by quoting Sir Isaac Newton’s First Law of Motion: “An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.”

My conclusion: force would be the jet engine.
