The NTSB hasn’t released its initial report but did verify that they’ve recovered the black boxes from both aircraft and initial data analysis confirmed the route of flight of both aircraft until the midair and that the Blackhawk was at an altitude of 300 feet when it collided with the CRJ, 100 feet higher than the maximum allowed when flying on Helicopter Route 4.NTSB also said that their initial data analysis showed that about nineteen seconds before impact, the crew of flight 5342 received an automated traffic advisory alert from the TCAS system. Data from the flight recorder showed the PSA jet pitched up about one second before impact, but investigators did not say whether this was an attempted evasive maneuver by the PSA pilots.
