Pacific Southwest Airlines Flight 182

In 1978, PSA Flight 182 collided mid-air with a private Cessna aircraft above San Diego, California. All 135 passengers in the PSA Flight 182 died, along with the two passengers from the Cessna plane and seven bystanders on the ground. The photo above was taken of the descending PSA flight just after their collision, an incident that may have been avoided if the pilots had taken the warning of a nearby Cessna seriously.

Paul Walker

Paul Walker was famously known as a main actor in the Fast and Furious movies, which essentially revolved around illegal and dangerous street racing. Walker and his friend Roger Rodas were killed in a single-vehicle accident after speeding in this very Porsche just hours after this photo was taken.
