A question during a job interview I had...

So I went to a job interview today, this is a govt IT job working at an AFB here in my city (civilian not enlisted). The interview went well but there was one question that kind of threw me off. Which was “Tell me this, how would you land a Boeing 747 on a hundred yard football field?” Now again this isn’t some piloting job this is working as a computer admin there. I’m just curious as why they would ask this one off the wall question? What do you think it means? Lastly, how would you land a 747 on a football field?
