For those who were living in San Diego 45 years ago today, and are still alive today, will never forget that day.
It started as a typical San Diego morning with clear blue skies and lots of sunshine.
But at 9:01am on September 25, 1978, everything changed when a Pacific Southwest Airlines 727 jetliner, Flight 182, collided with a Cessna 172 in the skies over North Park and crashed into the neighborhood below.
All 135 people aboard the PSA jetliner and seven people on the ground, along with the two people on board the Cessna died that day as nearly two dozen homes burst into flames.
At the time, it was the deadliest airplane crash to occur in the United States.
The people living in San Diego that day remember where they were when they saw the thick black smoke rising into the sky or first heard the news on the local news radio station at the time, which became KOGO.
The first responders will never forget the scene they encountered that day with some suffering from post-traumatic stress for years.
And those in the airline industry at the time, pilots, air traffic controllers and the FAA will never forget the crash because it led to big changes in the way planes are controlled near busy airport terminal areas like San Diego.
Every year since that day 45 years ago, a memorial is held at the corner of Dwight and Nile streets where the jetliner crashed.
And while it was a tragedy, the investigation into the crash of Flight 182 made the skies safer over San Diego.
