I am not sure exactly what state Sierra is in but I have been in and out of Oakland over the last few months and their fleet looks smaller then when I attended. Save yourself time and a whole lot of money, go to ATP. I have been to both schools and I cannot tell you how many ex-Sierra people I ran into at ATP. Unfortunately, they had already spent tens of thousands more then they needed to. Check out the ATP forum. Oh and by the way, this is not a shameless plug for ATP as I do not work for them, but I did have a fantastic flying experience there. Best of luck.
