EXCLUSIVEAstonishing videos show freediver squeezing through terrifyingly small holes and exploring sunken aeroplanes and buses

They're videos of someone holding their breath – that'll take your breath away.

Incredible footage shows freediver Kendra Vandergrift, from Florida, squeezing through terrifying small holes and exploring sunken aeroplanes and school buses.

In one video, she manoeuvres through a tiny tunnel while cave diving in Florida Springs. In others, we see her swimming through a small plane wreck and sunken school bus in a quarry in Ohio - all while holding her breath.

Kendra posts her underwater adventures on her TikTok account (@kendraunderwaterr), where she has gained a total of 66,800 followers and 3.5million likes. In the videos, Kendra wears a wetsuit, snorkel mask, and flippers, and films herself with a GoPro.

Her underwater videos have received a mixed response from followers, with many claiming they feel 'claustrophobic' just watching them.

However, Kendra told MailOnline Travel she 'loves the peace' of being underwater and enjoys exploring small spaces.

She said: 'The tighter the space underwater, the better. [However,] I always make sure I fully fit before I swim through.'

Kendra can hold her breath for up to three minutes, which took her three years of 'consistent training' to achieve. She added: 'Normally, my dives only last about a minute to 1.5 minutes.'

While Kendra primarily films herself while diving, she said she never dives alone and is always accompanied by two safety divers who know how to get her to the surface safely in case of danger.

She said: 'It's the number one rule while freediving. And always follow it! You never know what could happen.'

And Kendra's wildlife encounters prove this - she's come across otters, sea turtles, sharks, alligators and venomous cottonmouth snakes.

However, she claimed she's 'not really afraid' of the dangerous creatures, especially alligators, which she claimed 'normally stay hidden and leave us alone'.

She is also 'aware of her surroundings at all times'.

The 33-year-old, who began freediving in 2020, spends most of her days working at the Plantation Adventure Centre in Crystal River, Florida, as a manatee tour guide, where she teaches people to swim with the large mammals in a 'non-captive environment'.

The 'gentle giants' are protected under the Florida Manatee Sanctuary Act, and while they can touch humans, it's illegal to touch them back.

Sharing some advice to beginner divers, Kendra said: 'A common misconception about freediving is that certain people can't do it.

'With the right training and understanding, anyone can free dive. No matter your size, age, or gender.'
