 The majority opinion presented by the NTSB accident report determined that the cause of the accident was the TWA flight crew's inability to successfully abort takeoff procedures due to an excess of speed.The NTSB recommended revisions and expansions to airline abort procedures and new FAA regulations defining runway clearance and procedures, taking into account jet engine exhaust.In his minority report, Mr. McAdams' said that he would have found the probable cause of the accident to be the Delta crew's failure to adequately advise the tower of the proximity to the runway, and the tower's failure to request additional and precise information prior to clearing TWA 159 for takeoff.
