How have modern aircraft safety features improved compared to planes of the past?

Modern aircraft feature significantly enhanced safety features compared to older planes. They're constructed with tougher materials that better withstand crashes, with seats now able to endure up to 16 G-forces to keep passengers secure during impact events. Additionally, aircraft interiors are now manufactured with flame-retardant materials, which critically extends the evacuation window during fire emergencies. These advancements in materials and design give passengers valuable additional time to safely exit the aircraft in emergency situations, substantially improving survival rates during aviation incidents.
