Al Malmberg visits with Lt. Col. Heather 'Lucky" Penney on The World of Aviation.  On 9/11 of 2001, then 1st Lt. Penney was one of two fighter pilots who got airborne to defend the nations capital. There was one problem, neither F-16 was armed. How could they protect Washington D.C. with no weaponry?
