Could you survive a shipwreck in shark-infested waters?
That's what "Sharkwrecked: Crash Landing" explores in a special featuring hosts Paul de Gelder and James Glancy. The two divers were dropped from an airplane into the waters around Palau, an area in the Pacific Ocean of over 500 islands known for its shark population.
De Gelder, a veteran of the British Royal Marines, has already lost an arm and a leg in a shark attack in Australia. Glancy also has a military background as a onetime Australian navy diver.
Still, both men admitted even they felt frightened at times while shooting the special, which saw them spend 44 hours in open water.
"This is a wild place with wild animals and things can go wrong," de Gelder told Inside Edition.
"You start feeling dehydrated and ill very quickly," said Glancy. "And that's when bad decisions start being made."
"You're exhausted," added de Gelder.
Shark attacks have been making the news lately. In the Bahamas, 21-year-old Jordan Lindsey died last month after being attacked by three sharks while snorkeling. Her mother tried desperately to drag her to shore and out of harm's way, but she ended up succumbing to her wounds.
Off the coast of North Carolina, 17-year-old Paige Winter lost a leg when a shark mauled her in June. Her dad jumped into the ocean, punching the shark repeatedly until it released her.
"I just immediately just start beating it with everything I could," Charlie Winter told "Good Morning America."
"Sharkwrecked: Crash Landing" airs on the Discovery Channel on July 30 at 8 p.m. ET as part of Shark Week.
