The potential is there, but that video you linked is very misleading.
I call a CGI fake on that video.

That one is a little more realistic, with the physics & dynamics a little better representing the actual flight dynamics & kinematics of the plane.
And a F-35B wouldn't be the "first flight" anyways, since this was originally an experimental plane called the X-35B.
(X designates experimental in the development of planes, F for a final released version of a Fighter plane, C for a final released version of a Cargo plane, B for a final released version of a Bomber plane etc, etc.)
