I recently did this:
Inspired by something Scott Manley did in KSP interstellar quest Ep. 5. Now I want you to fly through the island tower too. (Note: through means that you are on one side of the tower, then inside the tower, then on the other side of the tower with the kerbal alive. See above for an example)
Rules: Kerbal must be in a seat/(if really brave/foolish) in a cockpit. At least the kerbal, or if brave/foolish the cockpit make it through, that's a pass, with a bronze medal
+1 points for every part of the plane that makes it through.
(Tip: try a carrier aircraft, kind of like this,
)
5 points: silver medal
12 points: gold medal
Entire plane/whaterver-veichle-you-are-using survives: Platinum medal.
Note: actual signature badges coming soon (or not)
