There should be anti-vehicle ditches(filled with gators! 8-) ) around every
airport.
Hitting a passenger jet with a .50BMG (single shot or semi-auto,10 round
magazine)will not be easy,and will have little effect,as hitting something
critical is unlikely.Probably go in one side and out the other,very little
damage.

Take your Barret, hide in the weeds 1/4 mile from the end of the runway and put
one shot in each intake as the airplane lifts off. Difficult shots, but not
impossible.
