United CEO desperately tries to reassure fliers that airline is safe despite ... trends now

The CEO of United Airlines is trying to reassure fliers that the company is safe following a string of concerning incidents involving Boeing jets. 

Scott Kirby sent an email to customers saying that 'safety is our highest priority and at the center of everything we do' according to CNBC - while Boeing's market value dropped by 12.15 percent over the past month. 

It comes after a series of terrifying incidents unfolded on United Airlines flights in recent months - from a wheel falling from an Osaka-bound jet early March to a panel blowing off a plane shortly after it took off from San Francisco last week. 

'Safety is our highest priority and is at the center of everything we do,' Kirby said in an email to customers on Monday. 

'Unfortunately, in the past few weeks, our airline has experienced a number of incidents that are reminders of the importance of safety.' 

The Federal Aviation Administration is investigating the worrying incidents, which Kirby described as 'all unrelated' in the email. 

Kirby said United Airlines is reviewing the details of each incident 'and using those insights to inform our safety training and procedures across all employee groups'.  

The aviation industry has come under the microscope after a string of recent mishaps unfolded, beginning with a door blowing off an Alaska Airlines Boeing 737 Max 9 on January 5. 

In the latest incident, a United Airlines plane from San Francisco built by Boeing was grounded Friday after it was found to be missing a panel after it touched down.

The plane is a Boeing 737-824, and successfully touched down in Medford Airport in Oregon despite the missing part. 

No injuries were reported and the Boeing aircraft was not new or a MAX, Jackson County Airport Director Amber Judd said.

The incident - only the latest from the embattled manufacturer - is the sixth involving a Boeing plane in 10 days. 

Judd further clarified the part fell off midflight, as feds continue to look into Boeing's production practices.

United Airlines, meanwhile, issued a statement, confirming that the 139 passengers and six crew members who had been on board were all safe.

It read: 'This afternoon United flight 433 landed safely at its scheduled destination at Rogue Valley International/Medford Airport. 

'After the aircraft was parked at the gate, it was discovered to be missing an external panel. 

'We’ll conduct a thorough examination of the plane and perform all the needed repairs before it returns to service. 

'We'll also conduct an investigation to better understand how this damage occurred.'
