March 6 (Reuters) - The head of the National

Transportation Safety Board said Wednesday Boeing has not

provided some documents and information sought in its ongoing

investigation into the Jan. 5 Alaska Airlines 737 MAX 9 mid-air

emergency.

NTSB Chair Jennifer Homendy said investigators have sought

the names of the 25 people that work on door plugs at a Boeing ( BA )

facility in Washington but have not received it from Boeing ( BA ). "It

is absurd that two months later we don't have it," Homendy said

at a Senate hearing.
