The war in Iraq is creating a shortage at home -- of night vision goggles.
That's hurting pilots who fly medical helicopters on the homefront. The NTSB has encouraged the goggles' use since 2006. But most are going to the front in Iraq and only about 25% of the medical choppers in the States have them.
Since 2006, 5 medical choppers have crashed, killing 16 people, in incidents investigators blamed on not having the night vision goggles on board. (AP)
