To land the SHERIDAN the quickest way before the asteroids hit your ship, go down the stairs to the M.O.M. console and look at the VIDEO CD. Next to the VIDEO CD on the left are two buttons saying ON and OFF. Press the ON button, go back up the stairs and head right. Open the door marked EXIT using the keypad and then turn right again. Open the last barrack door to the right and search the desk and cabinet for a PASS and RAW CD. Leave the room and go back to the M.O.M. console. Using the PASS on M.O.M.'s screen, select the topic SHIP STATUS, then the topic SENSORS and then M.O.M. will ask you to use the RAW CD in the VIDEO CD. Do it and then leave the M.O.M. console and go to the cockpit area. Talk with WILLIAMS and he will land the SHERIDAN automatically.
