 In April 2007, acting on a recommendation made by the NTSB during its investigation of Comair 5191, the FAA issued a safety notice that reiterated advice to pilots to positively confirm their position before crossing the hold-short line onto the take-off runway, and again when initiating takeoff.And in May, acting on another NTSB recommendation, the FAA advised that pilot training should include specific guidance on runway lighting requirements for take-off at night.The NTSB released several reports on January 17, 2007, including transcripts of the CVR and an engineering report.
