Change in altitude= Change in barametric preasure. This can used to trigger a device. Like the Lockerbee plane that exploded years ago.

Barometric triggers as in change of altitude like when balloons finally float high enough to burst. But that would be too high for bio wouldn't it? Sarin was tried by the people in Japan which didn't work, anthrax?? Gee where is my list of handy dandy biological poisons? This is really getting old, I wish someone in DHS would say something reassuring.

Thank you. And balloons would look so innocuous at the Superbowl or at other celebrations.

I'm still wondering if the 300 jihadists who were beginning their journeys and prepared to enter the afterlife- willingly were infected with smallpox and sent out to mingle in large cities.
