How long did it take for them to find that Airbus plane that crashed into the middle of the Atlantic Ocean about 2 or 3 years ago from supposed thunderstorm turbulence ?
I read that it was blocked air data ports plus a multitude of errors that caused that crash.
The debris from the Air France aircraft was found in a few days. Due to the depth of the water and the time it took to find the FDR, that took over a year.
