Capt. Clayton Osbon was charged by federal prosecutors Wednesday with interfering with his flight crew and has been suspended by JetBlue, pending further investigation.
Reuters reports the "black box" should allow investigators to compare conversations from the flight deck with statements and sounds from witnesses to paint a full picture of what happened during the flight.
A JetBlue spokeswoman said the crew had been interviewed by investigators and were given "down time."
During the flight, passengers reported incoherent and erratic behavior from the pilot, after his co-pilot had convinced him to go to the restroom.
