I guess I will put my 2 cents on this. From what I have seen, Sheikra has been having a few problems. I saw a few evacuations but I never found out what were the problems. The last evac I saw was last week where Sheikra was stopped at the block breaks before the second drop. I think that they tried to restart it but they could not, so they evacuated. A few hours later it was operating normally.
From what my sup told me we can get trained on how to evac people but from all these problems I think I will pass. I do not want to climb that high unless I'm strapped in to the coasters seat. lol
