Inspections for Boeing 737 jetliners are already underway after the government issued an order Monday. The Federal Aviation Administration ordered inspections on newer 737s immediately following a disaster in Okinawa, Japan last August when a bolt from the wing of a 737 pierced the fuel tank causing it to explode on the tarmac. All 165 people on board got out safely. Monday's order expanded to include older models. The Houston Chronicle is reporting that Continental and Southwest airlines have begun safety inspections. United and Delta also use 737s.
