Your video isn't working. Hey you are out of SLC, so am I. I own a 152 with the 125 horse conversion and I'm looking for people to split cheap time with me. It's out of airport # 2 if you or anyone else is interested.
I believe it is spelled "Immelman." This figure starts with a half loop to inverted flight. A half roll then results in horizontal upright flight. An inverted Immelman would start inverted, followed by a negative G push to level flight in the opposite direction. What was done in the video is an inverted pass, followed by a sloppy push to about 45 degrees nose high, followed by various rolls to a level position. Not any kind of recognised aerobatic maneuver, and a d**n stupid stunt if you ask me.
