The crew of a United Airlines flight were all fired after they refused to board a scheduled plane that had the words “Bye Bye” written into the dirt on its tail section. Now the workers are suing saying they should not have been fired.

I don’t know about you, but in this day and age when “bye bye” is written on a plane, one just might think it is a terror threat!!
The tail of the 747-400 aircraft bound for Hong Kong from San Francisco contained the words “BYE BYE” along with a “frowning or devilish” face, according to a court complaint.
The crew cited a federal whistleblower law that prevents an airline from seeking punishment on its employees if they raise questions of safety or security.
“These flight attendants refused to let an airline bully them into flying because of what they believed, correctly, was a security threat,” David Marshall, the attorney representing the crew, told Reuters.
Despite the message, the pilot, mechanics and security all attested that the plane was safe. Still, the crew refused to fly, and the trans-Pacific flight was delayed and eventually canceled. The workers were fired for insubordination July 14.
So, what do you think? Should they have been fired? Do they have a case?
