Only four individuals have been able to entirely spin, and he is one of them. Tas Pappas and Rob Boyce have both spun it, but have yet to land it. Tony Hawk, one of the world's most accomplished vertical pro skateboarders, hit the 900 after 10 failed tries at X Games V in 1999. He landed it successfully for the first time two years later at X Games VII in San Francisco. The 900 is considered by many to be the greatest trick in skateboarding. It is also one of the hardest tricks to do well. Only those who practice it repeatedly can hope to master it. No other skateboard trick comes close to matching its difficulty level. In order to perform this trick, you need to understand how gravity works. On any other board, the more weight you put on one side, the faster that side will roll away from you. But with a skateboard, this is not the case. The more weight you put on one side of a skateboard, the harder it is to keep it there because the board is now leaning into the trick. If you don't take out your phone quick enough, you'll fall off. That's why people call this trick "the death drop". In order to survive it, you need to trust your board and know that you can let go at any moment. Also, make sure you are wearing pants during practice sessions!
