• Victims' families and officials urge Congress and FAA to act on safety recommendations.
• NTSB issued 50 safety recommendations after a deadly midair collision.
• Many recommendations remain unaddressed, including mandatory ADS-B technology.
• FAA requests $22.4 billion to modernize air traffic control system.

The push for aviation safety changes may indicate a growing concern about air traffic control and collision avoidance. The mandatory implementation of ADS-B technology could enhance safety, but its implementation may face challenges due to budgetary and operational security concerns. The FAA's request for funding to modernize its air traffic control system suggests a significant investment in safety management, which could have long-term implications for the aviation industry.
