It would be very useful if the Department of Defense were to provide the American public with a list of the manufacturers of the hundreds of different systems that played into the killing of Osama bin Laden last week. Boeing Co. is almost certainly on that list since it is the third-largest defense contractor in America.

It makes a variety of rotorcraft, surveillance vehicles and a host of other lethal products that help make the American military the most feared and capable military in history. We don’t know which company makes the secret helicopters used in the assault on bin Laden’s compound, but we do know, as my fellow radio host Mark Levin noted last week, those choppers didn’t get procured and deployed since January 2009.
