A really great idea..And to answer the question again,it ONLY applys to those in the tower,and not in air..(out of the tower)..
I would also like to say that a safety net after the allotted time,however long it is,could cause a reminder to come up on screen and one would have to click it,something that says,,unless clicked you will be booted,something like that,and be delayed for like 15 seconds to possibly being a one min warning...????NO click,DAS BOOT"
