hardly, those things are heavy,coming down at full flap means they're touching down at 130-140kts IAS, you will soon stop in half runway. The use of arrestor hooks is more understandable in case of a high speed landing (i.e. hydraulic failure and no flaps/airbrakes)when u come down at 300kts and u need to slow the thing down properly and above all to keep it aligned with the runway. It was a redundant manouvre, and if anything they risked to crack the fuselage open with such a hard slam on the runway other than injure the crew. But hey, that's the fun of it, as we say:"any landing you can walk away from is a good one" and judging from how fast they ran out of the thing, that must have been a damn good one indeed
