Thor,
The action taken by the crew was successful. You have the result and you can try to simulate other actions to try to prove if, or if not, the actions taken were optimal.
Given the exact same circumstances, follow exactly what the crew did. We know that it works. Who knows if leaving the gear down would be safer? What would you do? If you were unlucky enough to be in the exact same position, would you back simulation or an actual event?
