Bungie used a feature called "recorded animations" to re-play a dropship being driven in and then flying out, with the script unloading the dropship in-between those animations. This feature has been rendered useless in the public version of Sapien, as Sapien does not accept player control input; this is needed so the game has animations to record.

The only other ways I could think of would be to get an AI to pilot the dropship, and then use command lists to direct it, or to actually animate the dropship in 3dsmax.
