The investigation that followed was extensive, with the FBI taking the lead. The agency interviewed numerous witnesses, analyzed the plane’s wreckage, and scoured the area where the hijacker was believed to have jumped. However, despite their best efforts, the hijacker’s identity and fate remained a mystery.

The authorities quickly sprang into action, and the plane was redirected to Seattle-Tacoma Airport. Upon landing, the passengers were released, and the hijacker’s demands were met. The crew, however, was kept on board. The hijacker then ordered the plane to take off and head for Mexico City, but with a significant twist – he instructed the pilot to fly at a low altitude and reduce the cabin pressure.

In 2007, the FBI officially closed the case, but not before releasing a few tantalizing details. The agency revealed that they had received over 1,000 tips and had investigated numerous leads, but ultimately, the case went cold.

As the plane reached an altitude of around 10,000 feet, the hijacker jumped out of the plane, using one of the parachutes he had demanded. The crew, still on board, was left to wonder if the hijacker had survived the jump. The plane, now empty except for the crew, landed safely in Reno, Nevada.
