BOSTON -- While the process isn't perfect, scanning machines do exist to detect liquid explosives like the ones purportedly at the heart of the terrorist plot broken up this week.
But don't expect the machines to be rushed into airports soon. Cost and logistical issues present challenges for these devices.
Consider work that's been done at Rapiscan Systems, part of OSI Systems. Rapiscan is developing four kinds of devices -- some based on technologies more than 10 years old -- that can detect liquid or gel-based explosives. Two that would work on carry-on bags already have been tested by the Transportation Security Administration and "could be deployed this afternoon," said Peter Kant, the company's vice president for government affairs.
But none are being used in the United States. Some are in place overseas, though Kant said those aren't in airports.
