What are some key questions investigators will ask about the Delta Flight 4819 crash landing?

According to a Delta pilot consulted by the correspondent, investigators will focus on why the plane landed nose-first instead of the proper back-wheel-first approach. Key questions include whether visibility issues prevented the pilot from seeing the runway properly, if weather conditions played a role, whether there were problems with the landing gear, or if other aircraft issues contributed to the unusual landing. These questions are particularly relevant because the video shows the aircraft touching down nose-first, which is contrary to standard safe landing procedures where the back wheels should make first contact with the runway. Investigators will likely interview both the pilot and air traffic control to determine exactly what factors led to this potentially dangerous landing situation.
