This is the moment an angry helicopter pilot reprimanded a tourist who grabbed a lever in the cockpit - that would have sent the chopper plunging into the Grand Canyon.<br /><br />Video shows the pilot grabbing the passenger's wrist and screaming "No! That will kill us!"<br /><br />The passenger had grabbed the helicopter's rotor brake - which is designed for use on the ground - and stops the propeller from moving.<br /><br />Cherlin Bijlsma, 27, from the Netherlands, was on holiday travelling around the West Coast of the USA.<br /><br />One of the pitstops was at the world-famous Grand Canyon, where she decided to take part in a helicopter tour.<br /><br />Commenting on the moment, Cherlin said: "We watched a safety briefing video - so they must have not paid attention." <br /><br />The footage shows the pilot grabbing the lever lightly and then almost instantly afterwards the woman grabs it herself, resulting in her being reprimanded.<br /><br />Cherlin added: "When the pilot scolded her I looked at her in between the seats and I saw that she smiled at the pilot. <br /><br />"It was an awkward smile. I’m not sure if she said anything back to the pilot. I did hear their voices on the audio, but I didn’t hear them at that moment.<br /><br />"The lady who grabbed the lever was there with what I think was her daughter. <br /><br />"It looked like she didn’t understand English very well."<br /><br />The tour group soon managed to get to the Grand Canyon and then made their way back to the base.<br /><br />Cherlin said: "When we landed my friend - who was also in my travel group - jokingly thanked the pilot for 'saving our lives'.<br /><br />"The pilot laughed while shaking his head, he said something like 'oh my, oh my'."<br /><br />The footage was captured on June 14.
