Hmmm
Imagine you are in a room with 3 switches. In an adjacent room there are 3 bulbs (all are off at the moment), each switch belongs to one bulb. It is impossible to see from one room to another. How can you find out which switch belongs to which bulb, if you may flip each switch only once and enter the room with the bulbs only once?
I had a sweet sim flight this morning. We got to play with aerodynamics. Did some high altitude stalls, a split-s, aleron (barrel) rolls, vertical loops, and a 100ft pass over the runway with a ground speed of 760 knots! (Mach 1.something)
