According to a story in the Puget Sound Business Journal, Boeing and forest products company Weyerhaeuser have conducted flight tests of an aerial firefighting system that drops water or retardant in cardboard containers that break apart in mid-air and release hundreds of water bombs.
I'm sure the idea holds water, but the US Forest Service remains to be convinced the system is safe. The story says aviation programme leader Carl Bamberger is concerned people will be upset if they "find Bambi konked out by a big box".
The Precision Container Air Delivery System was conceived by Boeing engineer William Cleary for use with the C-17, but according to the Business Journal the drop tests over western Arizona in early July involved an old Fairchild C-123.
