Contestants from ITV2 reality TV show, Celebair, threatened to walk out this week after show bosses made them resit a test.

The celebs had all previously passed the Civil Aviation Authority exam when bosses found out that they had taken a long boozy lunch immediately before the test. For safety reasons they then insisted that the exam was retaken by all.

Some of the stars were not too happy at the thought of a re-take and threatened to leave the show.

“They were up in arms because they’d all passed and couldn’t see why they had to bother to do the exam again,” an insider told the Daily Star. “But safety is paramount for the producers and they felt they couldn’t take a chance. They wanted to be sure they knew their stuff.

“They were on the verge of walking out until they were promised a day at a spa if they agreed to resit it.”
