Refueling midair doesn't work unless a special receptacle is built into the receiving airplane.
In truth, the Die Hard 2 situation would have taken care of itself.
They wouldn't run out of gas
As airplanes ran low on fuel (or simply, as they sensed which way the wind was blowing, and it's an airplane, they have instruments for that), the pilots would have said "Frak this felgercarb" and gone somewhere else.
By "low on fuel" I mean SOP is to have a divert/alternate airport already selected, such as Frederick ;), BWI, National, Winchester etc, or ideally another major airport that is an operating base for that airline or partner. They know how much fuel it takes to reach their divert airport, and to make one missed approach/go-around there and then land -- without invading their fuel reserve.
So they'd break out of the hold before that fuel point and go land at their alternate. If they missed approach at their alternate for a reason likely to repeat itself (e.g. crosswinds), they'd declare an emergency and go to a third airport, and to hell with customs and immigration!
Bad Guy doesn't have control of every airport. Also, military airports are usually available for emergency flights.
They wouldn't crash into the ground
The pilots would notice the ground coming up faster than expected, and go "oh hell no" and punch TO/GA. They'd then get on the radio and warn everyone else, and aviation radios aren't full duplex, so ATC couldn't have shut down plane-plane comms. Even if one aircraft managed to fireball, certainly no other aircraft would attempt that landing at that point, and certainly not ILS.
At that point, planes would've treated Dulles as cootie and taken their business elsewhere. The Northeast Corridor is a fantastic place to have that problem, because you have National, BWI, Philly, Newark and the NYC airports, all well connected via Amtrak's 125/150 mph Corridor service from Boston to Richmond, which gets a lot of people home, or easily to connecting flights at BWI or PHL (which have good Amtrak-air connections).
