Opened in 1978, this double-looping coaster from Schwartzkopf remains one of the premier attractions at Six Flags Over Texas.  It travels at a maximum speed of 60 mph and features some nice elements.  Seating two across in two rows with 7 cars for a total capacity of 28 riders, the train goes straight from the loading station up a 116-foot chain lift hill.  Once at the top, it makes a U-turn and traverses a small incline while approaching the first drop.  It then drops 105 feet at a 46-degree angle.  This is followed by two consecutive vertical loops, small hill and mid-course brake run.  From that point it makes a right turn, drops and veers left before dropping again.  The ride finishes with an additional hill leading into a helix. 

This coaster has stood the test of time well.  It’s not at all rough and with a maximum G-force of 5.9, it’s a force to be reckoned with.  Although I wouldn’t rate it extremely high on the thrill scale, it does offer a lively ride with some very nice pops of airtime.  Shock Wave is easily re-rideable and a lot of fun.  3 ½ out of 5 stars.
