Boeing panel that detached in mid-flight was not secured with screws, according to federal report. As the Federal Aviation Administration continues to review the company's processes, its new boss, Michael Whitaker, said it is clear that changes are needed in the way the Government oversees it.

The National Transportation Safety Board (NTSB) on Tuesday released its preliminary findings on an Alaska Airlines flight that was forced to make an emergency landing last month. A photo of the Boeing 737 at a factory in Renton, Washington, showed that the malfunctioning door panel did not have the screws installed in the door plug.
