Comment on Virginia plane crash investigators ask when pilot became unresponsive and why aircraft flew its path

By SARAH BRUMFIELD and MICHAEL BALSAMO (Associated Press) WASHINGTON (AP) — The pilot of a business jet that flew over Washington and crashed in a remote part of Virginia appeared to be slumped over and unresponsive, three U.S. officials said Monday, recounting observations by fighter pilots who intercepted the wayward flight. The revelations came as federal investigators trudged through rugged terrain to reach the site where the plane slammed into a mountain Sunday, killing four people.
