Major airlines aren't the only part of the aviation industry hit hard by last week's terrorist attack. Many flight schools are struggling to continue teaching in the face of flight bans enacted by the Federal Aviation Administration. Last night, the FAA lifted some restrictions on small aircraft... but kept a full ban on training flights in place. Bruce Smith is Dean of the University of North Dakota's School of Aerospace Sciences. He says until the FAA lifts the ban, UND's 900 flight program students are grounded. He says he doesn't know why the FAA hasn't lifted the ban.
