(UNDATED) - Some airport screeners are now roving the nation's airports using chemical swabs and bomb-detecting devices.
The TSA agents will stop random passengers and use the swabs to check for explosives.
The program was tried out at five airports after the failed Christmas Day bombing over Detroit.
Passengers at Indianapolis International Airport weren't enthusiastic about the new program.
Many said for the program to work, everyone would need to be swabbed and tested for explosives.
The new microwave-sized bomb detecting devices are said to be so strong, alarms sound for passengers who recently took heart medication containing nitroglycerin.
The TSA is banking $40 million next year that the new program is the answer to security at the nation's airports.
