The Tucson Representative introduced legislation two and a half years ago to combat the use of ultralight aircraft.  Resembling gliders with a small engine and propeller, ultralights are used by drug smugglers to carry narcotics across the U-S/ Mexico border. 

Giffords’ first bill passed the House, but was never heard in the Senate.   She cosponsored another measure this year that increases the punishment for using ultralights and gives Border Patrol agents more tools to interdict them.
