Air Florida accident, flight 90.

Hello again! 

After a few days, I’m here to tell you something new. Today I’m going to tell you what happened with the flight 90 of Air Florida. It occurs in 1982. A very cold day, one of the coldest.

The plane is being prepared to fly again. In the cockpit are the technic crew, is composed of the Captain and the first pilot, both unexperimented in the 737 airplane type.

The passengers are boarding, the cargo it’s already loaded and the last tasks are on the way.

One of them is the thaw service. Pilots are waiting for them cause without them, they aren't able to fly.

For win time the pilots consider to activate the reverses in the way to help, not knowing that the desition made, will be an enormous mistake. In consequence, the reverses froze the temperature sensor of the engine.

In addition, once the thaw service ended, anyone knew that the solution of the thaw agent was poor in front of the required levels.

When everything was apparently finished, they started the push-back. Running to the runway the accumulation of snow increased, helped by the airplane in front. The captain thought that the blast of that airplane will thaw his airplane, making a new mistake, not only the blast didn’t thaw but also helped the ice accumulation.

Once the aircraft was ready to take place in the runway the pilot asked the captain to repeat the thaw procedure but the captain didn’t want and continued with his thinks. At the same time, the pilot again sees that the instruments didn’t give normal parameter and once again the pilot advice to the captain and the captain didn’t react to this important information.

After all these factors we are able to see that it’s not just one mistake, it’s the result of a chain of bad desitions plus unexperimented pilots and a bad thaw service.

As you can imagine only a few seconds after taking off the airplane felt of the sky like a rock touching the land in a river after pass and kill people from a bridge.

The investigations cleared that the first and most important guilty was the Captain cause his performanceñ. Followed by the rest of the crew that didn’t advice about the new accumulation of ice after the thaw procedures. Guilt also of the thaw service and finally guilt of the delay on the ground that permitted to the ice to be accumulated again.
