A federal judge in Fort Worth will decide if Boeing should face criminal prosecution for two crashes that killed more than 300 people.

In the eight years that airlines have flown Boeing's 737 Max jets, two crashes killed 346 people. The Max debuted as a fuel-efficient version of Boeing's popular 737 but quickly became a symbol of safety concerns.

An executive also said that Boeing was still delivering missile-guiding systems and fighter jets to customers.

(Reuters) -The global aircraft leasing arm of Australia's Macquarie Group said on Tuesday it has purchased 30 Boeing 737-8 aircraft, in line with its goal to transition to more fuel-efficient, new generation models. Macquarie AirFinance did not disclose financial details of the deal, which marks its second direct order with Boeing.

A hearing in Texas could be the final chance for families of Boeing 737 Max crash victims to demand criminal prosecution of the company.

A U.S. judge on Wednesday held a three-hour hearing to consider objections to a deal between the Justice Department and Boeing that allows the planemaker to avoid prosecution on a charge stemming from two fatal 737 MAX plane crashes that killed 346 people.
