philg -- Today I showed a group of high school kids, teachers, and parents around Hanscom Field. They are planning to build a human-powered helicopter, hoping to hover for 60 seconds, and wanted to see a conventional helicopter. We ran into a U.S. Air Force colonel. I introduced him and told the kids to feel free to ask him why we weren’t able to win any of our current wars. Then I asked if it violated any Air Force policy to be both an officer and a member of Al-Qaeda.
