I took the Walt's California guided tour at DCA earlier this year. The guide spent 20 minutes explaining the details of Grizzly Peak Airfield and how it tells the exciting story of California's aviation and aerospace history. All of the buildings in Grizzly Peak Airfield were designed specifically to tell the story of 20th century aviation and its development, and it all culminates in the big hangar that Soarin' is housed in. Grizzly Peak Airfield is now placed in the year 1961, but has all the buildings tracing the history of California aviation all still there, but repurposed by '61.
In the early 1920's aviation took off (the tour guide's pun, not mine) in California with gearheads and tinkerers, and they were often based out of gas station garages. And by the late 1920's many garages were expanded with custom built garages made for biplanes, and the first open-air "control towers" were built at airfields. Humphrey's gas station represents that era, with a building that started as an early 1920's gas station and was expanded by the late 20's to include an airplane garage and small tower. The 1920's were a dynamic decade for aviation in California.
1920 gas station on one end, updated to 1961 tourist use...
Circa 1928 expanded station/airfield tower on the other end...
In the 1930's aviators were finally working out of custom built facilities made for aircraft. The first real "hangars" were born, and new California companies were setting up shop in them that would go on to great things; Douglas, Lockheed, etc.. The Grizzly Peak version of this 1930's long-low hangar architecture has been repurposed for... bathrooms!
Then the 1940's and the war arrived, and California aviation turned from civilian fun to wartime work to beat the Germans and Japanese with superior air power. The famous Quonset Hut design was invented by the Army Air Corps, and Quonset huts were built all over the place for airplane maintenance and manufacturing. Grizzly Peak's original World War II Quonset hut is now home to a hamburger stand and the local firefighting air brigade that protects California's forests; Smokejumpers Grill.
After America won the war the servicemen returned home and many got jobs in California's growing aerospace industry. The Space Race was on in the 1950's, and California was home to many big companies aiming for the moon and beyond. Giant Space Age hangars were built to house both the commercial jets under production in California, and the towering rockets for the nation's space program. The 1950's era super-hangar in Grizzly Peak Airfield is used to house the popular Soarin' attraction.
Which brings us to 1961 and the tourist-friendly Grizzly Peak Airfield. Which actually brings us to the 21st century and Disney California Adventure's story of California adventures. The tour guide told us the queue and interiors of Soarin' will be re-Imagineered in spring 2016 for a multi-month refurbishment prior to the new global Soarin' films debut. The re-design of Soarin's original 2001 queue will help strengthen the plotline and story of Grizzly Peak Airfield, and set up the plot of heading out on a great adventure on this tinker-toy like flying contraption inside the theaters.
It makes a lot of sense when the tour guide explains all the Imagineering behind it. But it can get lost on people just rushing through to get their Soarin' Fastpass on their way to Cars Land. Like most things in Disney theme parks, you have to slow down and take it all in to appreciate it. And it also helps if a pretty Disneyland tour guide explains it to you.
I asked the guide about the Epcot version and if it would be getting the global film at the same time (this was back before that news hit these boards), but she didn't have any information about the Epcot version. So I have no idea if the Epcot queue will be re-Imagineered for the new global movie.
