The 8-second delay may be attributable to donning crisis oxygen masks and/or cross-cockpit conversation about intentions although, we hasten to add, this is speculative. "There is no evidence of thrust reverser deployment in the data we have," Chairman Hall declared. As of this writing, investigators have not over and above recovered the cockpit voice recorder. uniform with this crash, the accident record of the 767 is among the best in the industry, as shown in a comparison of 20 airliners in the graphic below.
