Harrison Ford is giving Shia LaBeouf flying lessons.

Shia begged Harrison to show him how to fly a helicopter during the filming of 'Indiana Jones and the Kingdom of the Crystal Skull' - but soon regretted his high-flying ambitions.

A source said: "Shia was pestering Harrison to give him helicopter lessons. After the film wrapped, Harrison took Shia to Burbank Airport and they took off. But by the time they had landed, Shia had no stomach for a pilot's career. He came barreling out of the chopper and dashed for the men's room. He lost it."

Harrison reportedly found Shia's weak stomach for heights amusing and jokingly suggested the 21-year-old star should arrange another high-altitude masterclass.

The source added to the National Enquirer magazine: "When Shia emerged pasty-white and sweating, Harrison asked with a mischievous glint in his eye, 'So when is our next lesson?'"
