Can you fly a pelican in Halo 123?

Unfortunately, you cannot fly a Pelican in any of the three Halo games, at any point.

The only place that is likely possible is Halo PC/CE, where people make custom mods.

I hope this has helped you; if you have more questions, my Gamertag is below:

Gamertag: PyT Shad0w, Level 50

Can't fly one but you can ride on/in one in several levels by either jumping on top or sometimes pressing x shortly after being let out of one

Gamertag: Disench4nted

If you mod halo 2 you can, all you have to do is ftp your xbox, or use a 360 hardrive with sata cable.

well, in Bungie weekly update thay say you CAN on Reach, I just don't know where.
