yes but it's a secret
most maps have pelicans but u cant drive them you master cheif in or next to one during the story but thats only in the cutscenes
The map, Foundation, does not exist in Halo 3 and is only available in Halo 2.
Just dowload it for free at getdota.com.
Only certain Halo: Custom Edition maps have this feature, and on those few maps, only specially coded pelicans can pick up vehicles on specially coded pads. A nice example to play with would be the pelicans on the map "Coldsnap". If you park a warthog, tank, or ghost on the landing pad behind the pelican, you can pick it up from the pelican's pilot seat by maneuvering over it and pressing "q". Again, though, this only works with some pelicans on specialized landing pads. I recall one map having some pelicans that CAN pick up vehicles and some which can't; RPG Zulu Mod. It seems only the pelicans from the overhead cruiser can lift vehicles, though the landing pads at Fort Carillon below can also be used by those pelicans. Sorry for the complicated response, but it's a complicated matter!
