Gliders are definitely not 'lighter than air'
Re: "Foxx could push FAA to adopt glider warning rule," Editorial, May 22
Sorry, but I feel compelled to point out an error in your editorial that describes gliders as "lighter-than-air."
True, as they soar gliders may appear to be weightless. But unlike hydrogen or helium, they are most assuredly not lighter than air.
They fly by using the air...
