And with a headwind you can actually fly backwards lol
...you know it.....!! one time, flying over the mountains of western Virginia, I was facing a headwind that just about made my ground speed zero....! that was quite a trip..and, of course, the fuel tank started leaking, dripping a bit of 87-octane fuel on the wooden flooring underneath it....
I actually did fly backwards in a J-3 at Galveston TX airport
