Firstly, original suggestion credit to @trail jay . Reposted with permission with the intention to add detail/direction. Contact me via DMs for the message link for added context.
Background:
AEGIS is a multi-billion dollar company with a strong military presence and active conflicts. In the lore, the Corporation has had instances of reactor meltdowns and site destruction. So, with these instances, it would make sense AEGIS would utilize its assets to ensure individuals of importance to the corporation have a safe escape route if trapped in the facility.
Suggestion: The addition of a detachment of The Tower. After going up one level, there will be an additional door labeled "Emergency VTOL" proceeding down this hallway is a door labeled "VTOL". This door can be opened via a [L-3]+ keycard. Meaning, Site Control, ARD, and PKSF can access it. (Not sure about STHD's card level, assuming its [L-2]. You would enter a room with a closed panel over the roof with the AEGIS logo on it. The ToML+ would approach a scanner, similar to the one in booths, and scan their hand via holding out their keycard. Once the system as identified their rank, the roof would open up, taking about 10-15 seconds to open. Once opened, the ToML (and their PKSF protection if they elect to bring them) enter the VTOL, with the ToML driving. The VTOL would have to make it across the map towards jokeumbia, upon flying over jokeumbia everyone in the VTOL will 'escape' and the VTOL will despawn.
VTOL can only be used once every 30min, meaning, ToML+ can't escape that way every time.
