      >Honestly had no idea what a vapor cone was until I saw it in person yesterday. Pretty cool.

      >A vapor cone (also known as a Mach diamond, shock collar, or shock egg) is a visible cloud of condensed water that can sometimes form around an object moving at high speed through moist air, such as an aircraft flying at transonic speeds. When the localized air pressure around the object drops, so does the air temperature. If the temperature drops below the saturation temperature, a cloud forms.

    2. So I know the naked eye sees things at 60 fps, but I wonder if the quality of video improves or plateaus above that frame rate limit?

      In my opinion, fighter jets are the most aesthetically pleasing war machines. Their dramatic design elements always impress me, even though I’m not a millitarist person.

    4. Imagine if one of those boaters was asleep below deck and had a sonic boom right above them…
