This is a really interesting web site about the USS Macon, a large
airship that crashed off the California coast in 1935. It was powered
by eight large 560-horsepower gasoline powered German built Maybach
reversible engines. (Was Maybach part of the MB or DB company back
then?). And it carried airplanes it could launch and recover. Anyway,
the wreckage was located and lots of photos taken, some very interesting
history. These big airships were so cool.
