Falling Upwards - How We Took to the Air (Richard Holmes, 2013)

Kind of disappointing - the subject matter just isn't interesting enough to me to support all of the detail.  The author runs through the history of ballooning.

I was optimistic because of how interesting and useful I found this work by the same author.  Plenty of similarities in time period and subject matter.  But the earlier book covered a wider range of topics - this book didn't benefit from tighter focus.

The first balloon passengers were pretty amazed at how the world looked from overhead - that's cool because it's rather hard to imagine these days.

Early efforts to use balloons in war - including U.S. Civil War - not terribly effective.

Something I hadn't realized:  balloonists played a key role in maintaining communications between Paris and the rest of France during the German siege of 1871.  Not that it helped France a whole lot. (Victor Hugo heavily involved at this time - he returned from his "exile" once Napoleon III was out of power.)

Author wraps up with a tale of folks seeking to use a balloon to reach the North Pole.  Touching story, good finale to this era.
