It’s a bird! It’s a plane! It’s… an ad for cigarettes?! For the past 102 years, people have been using airplanes to turn exhaust into ads, political slogans, birthday greetings, and more. But where did this strangely brilliant idea come from? What kind of sorcery do pilots use to make it happen? And why is it at risk of becoming a lost art?

Which airport should you hang out at if you want to meet a mini-horse? Why is the art in the Denver Airport so evil? And are TSA agents more likely to search you if you're carrying an Almanac? Will and Mango investigate.

You don’t need to travel to find us on Instagram. Just go to @parttimegenius.

This week Will and Mango celebrate their own wonderful grandmas by paying tribute to a whole world of awesome grandmothers. From a cuddly graffiti gang in Europe, to a group of grandmas who advanced our understanding of marine science, to a few celebrities who never would have gotten where they were if it weren't for their Mamaws, here's to all the grandmothers and grandmother-figures we're so lucky to have in our lives.
