Boeing executives on Monday apologized to airlines and the families of the victims of the two deadly crashes that grounded the 737 Max jet, The Associated Press reported.

“We are very sorry for the loss of lives” in the Lion Air crash in October and Ethiopian Airlines crash in March, Kevin McAllister, CEO of Boeing’s commercial aircraft, told reporters at the Paris Air Show.

“I’m sorry for the disruption” to airlines from the grounding of the planes, McAllister reportedly added.

Boeing executives speaking at the event on Sunday reportedly defended improvements to the Max software that has been implicated in the crashes, while acknowledging they made a "mistake" in how the situation was handled.

The company has yet to receive regulatory approval on software fixes it has made to the aircraft to address the issues involved in the crashes.

Investigations continue into the precise cause of the crashes.

It has been widely reported that the angle-measuring sensors in both planes malfunctioned, alerting anti-stall software to push the noses of the planes down.
