When you have no chance for a mistake

Do you really ever have that chance when it comes to planes?

Google "Mangalore Table top runway" in India.. and that is a Civilian Airstrip !!

*grabs vomit bag* =X omg

Isn't this sort of a better option though? I'm no aircraft expert by any means, but the engines and such really don't do much when it comes to flying, they give the plane enough thrust to get it off the ground and get going but the wings really take over and give the plane the lift it needs to actually fly. Wouldn't doing it this way allow enough lift for the plane to take off while using less fuel to get it airborne?
