Another Boeing plane was involved in a minor aviation incident this week.

Reuters reported that a United Airlines Boeing 757 lost a landing gear wheel while taking off from Los Angeles International Airport (LAX) on Monday (July 8).

United Flight 1001 from LAX to Denver safely reached its destination upon landing, but the airline said that it would investigate what caused the event. According to FlightRadar24 data, the flight involved was a nearly 30-year-old Boeing 757. 

A Boeing 777 plane bound for Japan, also owned by United, was forced to return to LAX after losing a tire after takeoff.

Boeing Pleads Guilty

The incident is another development plaguing the aerospace firm for the past decade. 

VCPost previously reported that Boeing agreed to plead guilty to criminal fraud charges filed by the US Justice Department and pay a $243.6 million fine. 

However, families of the victims of the two Boeing crashes in the late 2010s are still disappointed with the plea deal, saying that it was neither enough to appease them nor enough to compensate them.
