Unruly air passenger

Hmm...
An elderly, reportedly 'very frail' gentleman going bananas being subdued with TKD?
I'm not quite convinced about the amount of martial arts needed here.
Then again, having experienced the power of psychiatric patients I do know that some may be extremely strong, even at an old age.

Story:
An elderly man on an American Airlines flight was restrained by passengers, including television's "Dr. 90210," after he got out of his seat and shoved a flight attendant late Monday, officials said.

Dr. Robert Rey, a plastic surgeon who practices martial arts, told The Associated Press he got out of his seat and intervened when he heard the man make a "big noise" as he pushed a female flight attendant toward the cockpit.

Flight crew members described the man as "very frail," a spokesman said. He had been scheduled to board a connecting flight to Singapore after landing in Los Angeles.
