 ==Explanation==
 {{w|Ingenuity_(helicopter)|Ingenuity}} is a drone-like helicopter deployed to the surface of Mars. It rode on the underside of the Perseverance rover and at the time of publication its protective housing had been released from the rover and it was being prepared for a flight in early April. The helicopter is supposed to take off after the rover fully releases it and clears its takeoff trajectory.
@@ Line 15: / Line 14: @@
 The total mass of the two vehicles is about 556 times that of the helicopter alone, meaning the unexpected lift effect 'described' would have to be several hundred times more effective than that anticipated, depending upon the factor of overdesign already built in to avoid an expensive marginal failure. It also seems to be trivially easy to balance the extremely top-heavy loading upon the small solar-panel that tops out the counter-rotating coaxial blades, which adds yet more questions of both the dynamic and structural performance, never mind questions about the available power to accomplish this and the later possibilities to recharge.

-The comic projects what might happen if the mission controllers activated the helicopter early. In this case, the process is approaching the point of detaching the part-deployed Ingenuity. Ponytail and Cueball are present in mission control when Cueball trips and hits a button that clearly triggers the Ingenuity drone to take off. Perserverance, still firmly above/attached is seen to easily ride atop it. The rover exclaims "Wheee!", presumably from excitement or happiness.

 In the title text, some character discovers powered flight is easier on Mars, which contradicts our current understanding [https://www.youtube.com/watch?v=GhsZUZmJvaM that powered flight is very difficult on Mars]. Mars may have less gravity, but Mars's atmosphere is 1% the density of Earth's. [https://www.youtube.com/watch?v=aYe3sIaNHVs It's so thin that you couldn't move a feather with a fan.] This is why the character mumbles his explanation of the science, because they know any explanation doesn't actually make sense.
