Final panic-stricken words of Challenger Crew before doomed space shuttle exploded 73 seconds into flight

The harrowing case of the Challenger rocket incident is something that haunts many to this day.

In 1986, NASA deployed the Challenger to travel to the Moon in a bid to do more research.

However, it exploded 73 seconds into its flight - in front of the eyes of stunned NASA engineers and millions watching around the world.

All seven passengers on board were killed when the spaceship disintegrated at 46,000 feet above the Atlantic Ocean.

Those on board were astronauts Francis R. Scobee, Michael J. Smith, Ronald E. McNair, Ellison S. Onizuka, Judith A. Resnik, Gregory B. Jarvis and teacher S. Christa McAuliffe who all perished.

Known as one of the worst NASA accidents, it was found to have been due to a mechanical fault, specifically the failure of two rubber O-rings to seal a joint between the two lower segments of the right-hand solid rocket booster.

Due to the severe cold temperatures, it opened a path for hot exhaust gas to escape from inside the booster during the shuttle's ascent.

This led to flames emerging from the hole which spread to a tank carrying liquid hydrogen and liquid oxygen which then exploded.

It was a major blow to NASA, who had been criticised for trying to accomplish too much with too little money, and also to the friends and families of those who died.

But there had been a lot of speculation as to whether the crew realised what was happening in the moments leading up to the explosion.

The truth? They didn’t until it was too late.

The final panic-stricken words from those inside of the shuttle was captured by the operational recorder which NASA shared.

Beginning with minutes before takeoff, the crew can be heard laughing and completing their routine checks to ensure that everything was reading as it should.

Running through the protocols and how to communicate stats, the crew seemed to be in their element until the final countdown began and then they were excited.

One person could be heard saying: “Go you mother.”

With one minute up in the air, they throttled up twice and another person commented: “Feel that mother go.”

However, seconds later it would be over.

Little did they know that something was wrong all along and was slowly making its way to flammable liquids.

Unfortunately, they realised at the last second when one person could be heard saying ‘uh oh’ before all data was lost to the operation room and the Challenger exploded into pieces.

The shuttle containing the crew remained intact and careened into the ocean, however due to the rapid pressure change and the crew not wearing pressure suits, it’s likely that they died before the impact of hitting the water because of the lack of oxygen.
