how about 'Heavy machine guns in NYPD helicopters'?
The NYPD began fitting police helicopters with heavy machine guns to shoot down terrorist airplanes about five years ago, after intelligence surfaced that al-Qaida was considering the use of crop dusters and other small craft for attacks, a senior city law enforcement official said Monday.
But while police officers have been trained to use helicopter-mounted .50-caliber machine guns against light planes, there was no intention to take down commercial passenger jets with such weaponry, said the official, who asked not to be identified.
