Pilot's viral sky message leaves people stunned after unexpected flight path

The pilot of the two-hour maintenance test flight over Northwest England traced the words "I'm bored" across the sky, with the unusual message and route appearing on the flight-tracking website Flightradar24.

Gary Leff, a Texas-based travel industry expert and author of the blog "View From the Wing," told Fox News Digital there is little cause for concern from his point of view because the flight was conducted to test the aircraft rather than transport passengers.

"This was a test flight, not a passenger flight," Leff said. "Writing 'I'm bored' takes a certain amount of skill and suggests the pilot was anything but distracted."

"Only a small percentage of flying on more modern aircraft is done manually at cruise," he said. "The workload above 10,000 feet is far less than during the takeoff and landing phases.

"'I'm bored' is an amusing way to express this."

The aviation company, Ravenair, told the BBC a flying instructor in his 20s was conducting a routine test flight after a replacement part had been installed on the aircraft.

"I think the pilot was literally a bit bored as it was just a test flight. Mind you, it was pretty skillful flying," Wes Barrett, operation manager, told the news outlet.

"He was a bit bored, but he probably had to concentrate a lot in the end to spell out the words."

Others praised the precision required to pull off the message. 

"Guys, [I] think he might have been a little bit bored," another commenter joked. "Credit for the amount of concentration and thinking required for this, though."

Another person wrote on Facebook, "Adult version of Etch-a-Sketch."

Fox News Digital reached out to Ravenair, based in Liverpool in the U.K., for comment.
