The National Transportation Safety Board (NTSB) has been actively working on recovering parts from the two aircraft involved in a collision near Washington Ronald Reagan National Airport on January 29. The incident involved a PSA Airlines Bombardier CRJ700 and a United States Army Sikorsky UH-60 Black Hawk helicopter.
As of February 8, all major pieces of both aircraft have been recovered and moved to a secure facility for examination. "Investigators will be looking for witness marks on the aircraft that could provide clues to the angle of collision," said an NTSB spokesperson. Additionally, the CRJ's Traffic Collision Avoidance System (TCAS) and other avionics from the Black Hawk have been retrieved.
Despite these recoveries, investigators warned that further debris might be identified underwater through Light Detection and Ranging (LiDAR) technology conducted with assistance from a National Oceanic and Atmospheric Administration (NOAA) aircraft. NOAA has reportedly been targeted by the Elon Musk-led Department of Government Efficiency, according to Representatives Jared Huffman and Zoe Lofgren.
