final report that concluded that the probable causes were a fire of undetermined origin, the flight crew's underestimation of the fire's severity and conflicting fire-progress information given to the captain. This report also found that the flight crew's "delayed decision to institute an emergency descent" contributed to the severity of the accident. Outcome and revised report Captain Cameron later said: After the NTSB issued its report, a number of commercial pilots and airline personnel petitioned the NTSB to revise its report. In addition, First Officer Ouimet sent the NTSB a detailed defence of the crew's actions, including the decision to land in Cincinnati instead of at Standiford Field Airport in Louisville, Kentucky, the airport closest to Flight 797 when the crew first declared an emergency. Ouimet stated that Louisville was too close to be able to descend from cruising altitude to an emergency landing safely, and even landing in Cincinnati was a questionable proposition given Cameron's difficulties in controlling the plane. In January 1986, after reviewing Ouimet's missive and reevaluating the available data, the NTSB issued a revised version of its accident report. The revised report included Ouimet's explanation of the landing decision. The report was still critical of Cameron's decision not to inquire about the fire itself. However, in its revised report, the NTSB revised its probable-cause finding to describe the fire reports given to Cameron as "misleading" instead of merely "conflicting" information. The NTSB also removed the word "delayed" from its description of the pilots' decision to descend, instead listing the "time taken to evaluate the nature of the fire and to decide to initiate an emergency descent" as a contributing factor. The crew of Flight 797 were later honoured by multiple Canadian aviation organizations for their heroic actions in landing the plane safely. Safety recommendations As a result of this accident and other incidents of in-flight fires on passenger aircraft, the NTSB issued several recommendations to the Federal Aviation Administration (FAA), including: Safety Recommendation A-83-70, which asked the FAA to expedite actions to require smoke detectors in lavatories. Safety Recommendation A-83-71, which asked the FAA to require the installation of automatic fire extinguishers adjacent to and in lavatory waste receptacles. Strong recommendation for expedited FAA rule changes mandating that all U.S.-based air carriers install (or improve existing) in-cabin fire safety enhancements, including (but not limited to): Fire-blocking seat materials to limit both the spread of fire and
