Boeing Co. heads to court on Wednesday to dispute a request from lawyers representing victims of a 737 Max crash for documents related to the aircraft's design, development and two fatal disasters involving the now-grounded plane.

Chicago-based Boeing faces around 100 lawsuits by families of 157 victims of a Ethiopian Airlines 737 Max crash on March 10, five months after a similar accident on a Lion Air flight that killed 189 people.

Lawyers for the victims' families are asking why Boeing and U.S. regulators allowed the Max to continue flying after the Lion Air disaster and whether the planemaker hid materials from crash investigators.
