"Modern High Power Rocketry 2" book

I'm putting the finishing touches on the big "torpedo" as one friend calls it and was searching for the latest information on vent hole and static port sizing.  These holes are drilled into the airframe to acclimate internal and external pressure and prevent failures.  In any event a Google search revealed an almost complete preview of the book Modern High Power Rocketry 2 by Mark Canepa.  I marvel at how thorough this 'preview' is and was so impressed with the content I bought it from Amazon on the spot.  Great stuff, Mark!
