The recording shows an air traffic controller asked a Birmingham Airport Authority worker about reopening the runway less than two minutes before the Airbus A300-600 jet went down on Aug. 14.
The main runway was closed for maintenance, and the UPS aircraft attempted to land on a shorter runway. The jet clipped trees and slammed into a hill near the runway.
The recording shows a cargo carrier from UPS competitor FedEx landed safely on the main runway just moments after the crash in Alabama.
The audio is posted on the Federal Aviation Administration's website.
