some passenger returning from either India or Italy. Or maybe he burped.

This was just a case of the machine giving a false positive.....Hopefully soon we will be able to get better equiptment so that this won't happen again.

I wonder what other common items can set it off.
|Quoting PHLJJS (Reply 6):|
CTX machines have the ability to let you see a 3D image of the bag and the suspect item and sometimes you may be able to clear the bag by looking at it at a different angle. Checkpoint Xray machines have no such ability. The Officer may elect to take the bag and hand search it and ETD swab test the bag to clear it
|Quoting PHLJJS (Reply 9):|
This incident did not happen at a security chekpoint. It occured in the lobby, in front of the ticket counter with a passenger's checked bag not his carry-on. ETD tests are usually done if the bag is reported to be suspicious by the CTX machine.
