Open Fort Zancudo hangar?

[DarthPungz]

I have seen a few videos with the large hangar at Fort Zancudo having open doors, is this an edited map thing or is this something that I can do with a trainer or by modding a file?

Thank you for the assistance.

The onlinemap has this feature
you can load onlinemap with any trainer
