The cockpit voice recorder data on the Alaska Airlines Boeing 737 MAX 9 jet which lost a panel mid-flight on Friday was overwritten, U.S. authorities said, renewing attention on long-standing safety calls for longer in-flight recordings.
National Transportation Safety Board (NTSB) chair Jennifer Homendy said on Sunday no data was available on the cockpit voice recorder because it was not retrieved within two hours - when recording restarts, erasing previous data.
The U.S. requires cockpit voice recorders to log two hours of data versus 25 hours in Europe for planes made after 2021.
The industry has been wrestling with the length of cockpit recordings since the disappearance of a Malaysian jet in 2014.
Although the Boeing 777 has never been found, the loss of MH370 sharply increased efforts to monitor the longest possible modern flights and where necessary recap earlier flights.
In 2016, members of the United Nations' aviation agency, the International Civil Aviation Organization (ICAO), recommended a 25-hour recording on planes manufactured from 2021, in line with the period of time already used for keeping flight data.
"There was a lot going on, on the flight deck and on the plane. It's a very chaotic event. The circuit breaker for the CVR (cockpit voice recorder) was not pulled. The maintenance team went out to get it, but it was right at about the two-hour mark," Homendy said.
The plane's flight data recorder and cockpit voice recorder were sent to NTSB labs on Sunday to be read but no voice data was available,

Although today's recorders use computer chips inside "crash-survivable" containers able to withstand g-forces 3,400 times the feeling of gravity, critics say the capacity for recordings housed inside them remains less than an ordinary cellphone.

I was an adult and watched that..
Yep, maybe.
Or, if the roll was at the end, or if the mechanism was jammed and would not allow pulling to a fresh section.
I may even have a roll of fresh towel, in some safe place.
