Here's the audio file from the AAL1357 emergency aircraft from this morning. The flight had problems with their navigation equipment and had to return to JFK shortly after takeoff. They landed without incident. The audio is from the time AAL1357 declared the emergency on ZNY 128.3 all the way to the landing at JFK. It has been condensed and edited to include all the relevant transmissions and remove a lot of the dead air.
