What recent aviation incidents have raised concerns about air travel safety in the United States?

Recent incidents have significantly heightened concerns about U.S. air travel safety. Just three weeks after a fatal mid-air collision between an army helicopter and a passenger jet over Washington D.C., a Delta Airlines crash landing occurred in Toronto. These incidents have reignited public worries about aviation safety standards. The situation is particularly concerning due to the nationwide shortage of air traffic controllers in the United States. This staffing crisis has exacerbated fears about the overall safety infrastructure of American aviation, raising questions about whether current systems can adequately protect passengers amid these workforce challenges.
