So what do you do if you missed your exit? Looks like this one just missed the turn and instead of calling for a tug, just a little bit of reverse and problem solved
I know powerbacks were common back in the 70's and 80's but were abandoned for a number of reasons. Looks like the crew was under pressure to make the turn (notice the tire smoke just before the turn).
