WASHINGTON (AP) — A Delta Air Lines plane nearly landed on a taxiway that was occupied by another plane at Hartsfield-Jackson International Airport in Atlanta, federal accident investigators said Wednesday. The National Transportation Safety Board said it has opened an investigation into the Nov. 29 incident. Delta flight 2196 had been cleared to land and initially lined up with a runway, but about a mile from the airport the plane began to veer left and lined up with a taxiway where another Delta plane was waiting, according to a preliminary report by the board. The Boeing B737, which was arriving from Indianapolis, descended to about 100 feet off the ground before aborting the landing and circling back for another try, the report said.
