Balloon Flight

Today's picture shows Albert Leo Stevens after his balloon is aloft. Yesterday we saw him preparing for launch. In this picture we see the entire balloon, and we can tell that in fact the balloon is a gas balloon, not a hot air balloon. The picture was taken in 1911, so most likely the balloon was filled with Hydrogen. Hydrogen has greater lift than helium, but of course one must be concerned that Hydrogen is a highly explosive gtas.


  1. As a child in the early 60's I remember the county fair had 'balloon jumpers'. We lived several miles away but would stand out front of our house where we could watch them ascend in a large round balloon. When high enough, they would collapse the balloon, releasing a huge plume of black smoke, and parachute back down.

  2. Ah, yes, hydrogen, Hindenburg, oh the humanity.
