Some superpowers sound cool, but really suck, take flight for example, In truth, flying isn’t as glamorous as it seems. To avoid birds, bugs, and other low-altitude pests (buildings, antennas, etc), you would need to fly a few thousand feet in the air. And for every thousand feet you go up, the temperature drops 1.65 degrees Celsius (3.0 degrees Fahrenheit). At 30,000 feet, you’re looking at an outside temperature of -23.8 degrees Celsius (-31 degrees Fahrenheit). You can bundle up to beat the cold, but make sure you have enough room for your oxygen mask; at 30,000 feet, the air is so thin that you’d pass out in seconds from oxygen deprivation. Now that you’re safely flying with your parkas and oxygen tank, remember not to break the speed of sound. In doing so, the friction of the molecules in the atmosphere hitting your body will create incredibly high temperatures, incinerating you despite the frigid temperatures. All in all, it’s a much safer bet to leave flying to the birds.
