While billionaires may have the resources to build their own jet airports, they can't simply place them adjacent to military airbases due to national security concerns and regulatory restrictions. So, where do these ultra-wealthy individuals fly their private jets from? If they the Air Force base for their takeoffs and landings, it suggests a level of access and a close relationship with the military that is uncomfortably close
Those national security concerns and regulations shouldn't exist in the first place.
Those billionaires shouldn't exist in the first place, either.
Maybe the investors have inside knowledge that the air force base will be closed sometime in the next few years.
