xkcd's Interplanetary Cessna and Trajectories http://ifttt.com/images/no_image_card.png

Earlier this week, the webcomic xkcd published a "What If" scenario asking how a Cessna 172 Skyhawk would fly on different planets in our solar system. No offense to xkcd's excellent author, Randall Munroe, but our physics blogger Rhett Allain took exception to his inaccurate trajectories of the Cessna's flight path on airless planets and moons. Here's how he corrects things with a nice dose of physics know-how.
