Well, the rain only lasted about 20 minutes and, as you can see here, the Boeing 307 Stratoliner has finally arrived. The Stratoliner's arrival was delayed by one day due to carburetor problems in one of its engines. The big Stratoliner seems to dwarf the Sukhoi Su-26 and Cap 232 in the foreground. Later, you'll see the Stratoliner get similarly dwarfed.
This Stratoliner is the sole remaining example of the world's first pressurized airliner. Due to WW II, only 10 were built. This particular Stratoliner has had a somewhat troubled recent history. After an expensive six-year restoration project, and after appearing at Oshkosh in 2001, the plane was ditched in Elliott Bay just outside of Seattle, Washington during a routine practice flight. So why was it ditched? Well, it ran out of fuel. Bad show all around.
The good news is that Boeing and a group of about 70 employees and volunteers got together and restored the plane again. After this year's show, the plane will make a beeline for Dulles International Airport outside of Washington D.C. where it will be retired to the new National Air & Space Museum annex.
