My memory's going faster than the veterans here (born 1963). I'm sure I posted these questions before and can't find the thread. 1. Which type of roll actually shifts a single-engined fighter's forward axis to the side, a snap roll or a barrel roll? 2. Which type of roll goes with and against the propeller's direction? 3. Which type causes a plane to lose altitude (both?) 4. What type of roll does a fighter do to shake off an enemy fighter that's right on his tail and starts firing?
