I’m done being serious for the week so thought I’d share some additional posts. In this week’s What If?, Randall Munroe discusses the possibility of flying a Cessna airplane above various Solar System bodies. These articles are usually pretty funny as they tackle some of extremely off-the-wall questions. My favorite line, though, is near the bottom, in response to flying a plane on Titan:

If humans put on artificial wings to fly, we might become Titan versions of the Icarus story—our wings could freeze, fall apart, and send us tumbling to our deaths. But I’ve never seen the Icarus story as a lesson about the limitations of humans. I see it as a lesson about the limitations of wax as an adhesive.

Such an engineering response! I love it!
