Amazing space footage from a long lost weather balloon Two years ago, aerospace systems engineer Bryan Chan and his friends launched a weather balloon equipped with a GoPro and a cellphone, into space. They released the balloon near the Grand Canyon and were curious to see what video they could retrieve once the camera fell back to earth. But, they couldn't find the balloon as they had planned. Two years later, an Arizona hiker found it and the camera and managed to contact one of Chan's friends. Finally, the team were united with the long lost ballon and the video they uncovered exceeded all their expectations. This video here shows their launch preparations and of course the short journey into outer space. Pro BMX rider flims his crazy journey through New York In this amazing video called 'GO!

Massive humpback whale almost crushed kayakers In California, two kayakers had a near death experience with...a humpback whale. How often can you write a sentence like that? Anyway, the kayakers -- visiting from the UK -- seemed to be minding their own business when all of the sudden the mammal breached and landed on top of them. A whale-watcher with Sanctuary Cruises captured the scene on camera. At first, the whale-watcher was so excited with having recorded the breach that he exclaimed, "I got him!", but then realised two people may have just been crushed to death. One of the kayakers later told The Telegraph , “It felt like being in an avalanche, like a bus landing on us,” Luckily, the only damage it caused was a dent in the British couple’s rented kayak.
