Upgrade engines by lighting all three lane lights on the launch ramp area. You can control the 
location of lit/unlit lights by hitting the flippers, just like the way you can control the ones
at the top of the board. The easiest pattern of play is to use the left flipper just as the ball
is entering the flipper, to pop it onto the launch ramp. Launch Training is therefore the quickest
way to make Ensign. Make it a habit to always go back for two repeat shots on the launch ramp for
a good point booster. Note: A flipper hit on balls being ejected from the hyperspace tube can 
fairly often send them back there. You also get a bonus for this repeat hit if done immediately.
