Blimps then, Guppies now at the Tillamook Air Museum

The Tillamook Air Museum's cavernous Hangar B is one of the largest wooden structures in the world. It once held a squadron of K-class blimps. Here's how those airships looked then, and how their home looks now.

Tillamook Air Museum

The gigantic Hangar B, once home to a squadron of patrol blimps, now houses the Tillamook Air Museum

My trusty rental car, after bravely letting me drive it through snow and sleet, offers some perspective of how big this building is.

And going

This is from the same spot. It keeps going and going...

Inside is quite dark. There are lots of lights, but the space is so huge and the surfaces so dark, that they don't do enough.

Last Corsair

This is the last A-7E Corsair withdrawn from military service. It was stationed on the USS John F. Kennedy from the late '70s to the early '90s.

View from the Tomcat

Stairs let you look inside the cockpit of this F-14, but the low light and reflections didn't make for a very good photo. On the right you can see the museum's collections of other cockpits and cockpit trainers.

This is the cockpit trainer for an F-8. You can sit in many of the cockpit trainers.

The Alenia C-27J Spartan is not an aircraft you see often in museums. It uses engines and some other parts from the larger-but-visually-similar C-130

This particular aircraft was built in Italy, flown by the US Air Force for five years, and then after some time mothballed at AMARG, it was sold to a private owner, who loaned it to the museum.

Space doors

The hangar is quite dark, so when the sun breaks through the Pacific Northwest clouds, the windows becoming blinding (and a hassle for photography).

Clouds clearing

It was raining when I first arrived, and after a brief downpour while I was inside, the skies cleared. Hangar B looked far more ominous with the cloud cover, however.

The doors are 120 feet (36.6m) high. Each of the six segments weigh 30 tons.

Mini Guppy!

I love weirdly proportioned cargo aircraft, and the Aero Spacelines Mini Guppy is certainly that.

Baby brother

The Mini Guppy was the smaller, younger sibling to the original Pregnant Guppy and larger Super Guppy specialized cargo craft. There's a Super Guppy at the incredible Pima Air and Space Museum, which we've also toured

Boeing base

All three Guppy aircraft were built using parts borrowed or adapted from Boeing 377 Stratocruisers. This one carried, among other cargo, the Pioneer 10 space probe and a Goodyear Blimp stationed in Europe.

Cargo hold

The Mini Guppy's fuselage was built from scratch, and is wider than the 377 it's based on.

The cockpit is basically the same as a 377. The nose on the Mini Guppy is fixed, with a swing-open tail for cargo. The Mini Guppy Turbine, using more advanced engines, had a swing-open nose.

Hangar B

As large as the Mini Guppy is, it's dwarfed by the giant Hangar B.

Here's the first in a series of historical photos I've included to provide more context for this fascinating museum. Hangar B was the first of two blimp hangars built at Naval Air Station Tillamook, and was completed in 1943.

Due to wartime metal shortages, it was constructed almost entirely of wood.

Hangar B was constructed first, and took 10 months to build

Without the weather and other delays that plagued that construction, Hangar A took less than 6 weeks. It was destroyed by fire in 1992.

Over 130 K-class blimps were built by Goodyear before and during WWII. (Catalog #: 80-G-K-13315)

Unlike most larger airships, the K-class was small enough for its mooring mast to be mobile, towed by a tractor in this case. (Catalog #: 80-G-K-13314)

Blimp K-87 attached to a mobile mooring mast at NAAS Quillayute, Washington, circa 1944-45. This is now the Quillayute Airport. (Catalog #: 80-G-K-2448)

The German submarine U-858 near Cape Henlopen, Delaware, in May 1945, after surrendering at sea. K-class blimps were primarily used as antisubmarine patrols. The helicopter is a Sikorski R-4, aka the HNS-1 in Navy parlance. (Catalog #: 80-G-K-3319-A)

Squad goals

Tillamook's Squadron ZP-33 had eight K-class blimps.

Now we're back to current photos I took myself during my visit. Not filled with big blimps, the 7-acre (2.8 hectares) floor space seems to go on forever.

Open sesame

Some other blimp hangars had clamshell-style doors. Hangar B's ride on railroad tracks.

Seeing up close that it's made from wood makes it even more peculiar -- and impressive.

W-a-a-a-a-a-a-y up near the top, you can just make out two narrow catwalks that run the length of the hangar.

The museum is currently restoring the fuselage of a Convair 880. This is a pretty rare airliner, and this is the only example on the West Coast.

The museum's MiG-17 was built in Poland.

Train too

This 1917 Heisler locomotive looks almost toy-like in this huge open space.

Roughly halfway

This is taken from about halfway down the hangar. The rest is currently used for storage.

Alien invasion

The only blimp... well, balloon, in the museum. This is much smaller than the K-class blimps that lived here.

44 of 56 Geoffrey Morrison/CNET

Big blimps

The K-class is a blimp, or non-rigid airship. Essentially it's a formed balloon with a fixed control car. 

Semi-rigid airships have a stiff keel, but the rest of the gas-holding envelope is only supported by its own internal pressure. 

Rigid airships, colloquially "Zeppelins," have an internal metal framework.

Most of the museum's remaining aircraft are housed in a tent erected within Hangar B.

I love Burt Rutan's designs. This Long EZ was home-built in the mid-'80s.

Pump room

The Hangar's original helium pump room. Helium is heavier and more expensive than hydrogen, but infinitely less dangerous

Arctic explorer

The museum's Cessna 180 is one of two planes that landed at the North Pole, the first light aircraft to do so.

French German

This is a French-built and engined Nord Noralpha, which is based on the Messerschmitt Bf 108 civilian aircraft from the 1930s. 

51 of 56 Geoffrey Morrison/CNET


At first glance I thought this was a T-37, but it's the visually similar British BAC Jet Provost

52 of 56 Geoffrey Morrison/CNET


Another oddball aircraft in a museum that has a lot of them, this is a Fouga CM.170 Magister, a French two-seat trainer jet. This specific example was actually built in Finland.

Twin rotor

Baby Lear

The museum's Learjet 24 was owned and flown by Cal Worthington, a famous (on the West Coast anyway) and extremely successful car dealer who flew B-17s in WWII and won, among other medals, the Distinguished Flying Cross.

Tucked in at the very end of the hangar-within-a-hangar is a lovely A-26. I wish it was easier to get a better look.

Mini Guppies and big hangars

The Tillamook Air Museum is small, ironically in a huge building. The history of that building and several of the aircraft make it worth a visit, if you're nearby. I combined it with a mac and cheese lunch at nearby Tillamook Creamery and the Evergreen Aviation & Space Museum in McMinnville, Oregon (phototour coming soon) for a busy but excellent day.

For more info about this tour, Hangar B, and the patrol blimps that called it home, check out Ghost blimps haunt a humongous hangar at the Tillamook Air Museum.
