It did not look to me like a gravity launch would have worked at the
airport in the commercial considering how close to the end of the

the glider released the rope and how hard (apparently) the car was
trying to pull. Still it was a heart-pounding video...

The hardest part was to keep the Antares on the ground as long as
possible (they were using negative flap settings to achieve that).

With an un-faked launch it would have been airborne within a couple
of
hundred feet.

That is much more like what I thought it should be from my own
personal experiences.. They had to make up some drama for the
commercial...
