XB-36 tires

Two years ago, in 2013, I visited the Pima Air and Space Museum near Tucson, Arizona. One of the airplanes that really catches your attention in it is the bomber Convair B-36 Peacemaker, with its 10 engines: six turnin’ and four burnin’ (I wrote a post about it here).

Ten engines: "six turnin' and four burnin' ".

When I wrote that post, I received the following comment from a reader, Ian C.

If you are ever back on this side of the pond, the National Museum of the Air Force has an XB-36 tire. It is just ridiculously large.

Last year, in 2014, we travelled again to the USA and this time we visited the National Museum of the Air Force (1) in Dayton, Ohio.

Let me close the loop by showing you this famous tire accompanied by some facts about it.

XB-36 tire

From the Wikipedia:

The XB-36 featured a single-wheel main landing gear whose tires were the largest ever manufactured up to that time, 9 feet 2 inches (2.79 m) tall, 3 feet (91 cm) wide, and weighing 1,320 pounds (600 kg), with enough rubber for 60 automobile tires. These tires placed so much pressure on runways, the XB-36 was restricted to the Fort Worth airfield adjacent to the plant of manufacture, and to a mere two USAF bases beyond that. At the suggestion of General Henry H. Arnold, the single-wheel gear was soon replaced by a four-wheel bogie. At one point, a tank-like tracked landing gear was also tried on the XB-36, but proved heavy and noisy and was quickly abandoned. (2)

Pima Air and Space Museum

Pima is a county in the South of Arizona, where the city of Tucson is located. Tucson is home of the Davis-Monthan Air Force Base, where the US Air Force’s 309th Aerospace Maintenance and Regeneration Group (AMARG), known as “The Boneyard”, is located. I wrote about the Boneyard in a previous postIn order to visit the Boneyard, you need to visit the Pima Air & Space Museum and that is how I got to know about the museum.

The description of the museum from their website states (the emphasis is mine):

“The Pima Air & Space Museum is one of the largest aviation Museums in the world, and the largest non-government funded aviation Museum in the United States. You’ll see more than 300 aircraft and spacecraft including many of the most historically significant and technically advanced craft ever produced, both from the United States and throughout the world.”

The museum has 6 hangars and one space gallery, plus an impressive exhibit outdoors, which can be visited with a tram or on foot (or both). You can see in the map below the arrangement of the museum:

Together with the plan the visitor is handed an inventory of the aircraft on exhibit and where are they located (in which hangars):

As you can see from the inventory above, the list of aircraft exhibited at the museum is simply impressive, overwhelming. Add to that, that in this museum you can get as close to the aircraft as you wish.

In the website of the museum you can find brief explanations of each of the aircraft on exhibit (here). This aircraft index can be surfed very handily ordering the aircraft by different criteria. The information about them includes some technical specifications, a brief historical explanation and a picture of the aircraft (I would almost say that it makes up for a visit of the museum). A very good job on the part of the museum curators.

Some of the highlights (in my opinion) of the museum:

Find some pictures I took of some of these aircraft and others in the slide show below:

The Pima Air & Space Museum has also facilities to restore the aircraft they get and bring them to a decent status to be put on exhibition. Some of the aircraft are on loan from the US Air Force Museum.

Within the museum there are plenty of US armed forces veterans willing to share with you detailed explanations or anecdotes from any of the aircraft. The tram visit of the outdoor exhibit is guided by one of these veterans… no need to say that the experience is fantastic.

It goes without saying it, that I strongly recommend to visit this museum as it is one of the best aerospace museums that I have ever visited. Couple that with the visit to the Boneyard and it is definitely a must for aerospace aficionados.

Finally, some tips to visit the museum:

  • plan your visit as early as possible (doors open at 9am),
  • allow yourself no less than 5 hours to comfortably visit the museum,
  • if the visit is in summertime, bring a bottle of water with you (which can be refilled in any of the many sources inside the museum),
  • plan to have lunch in the museum,
  • book yourself a place both in the tram to visit the outdoor exhibit and in the bus to visit the Boneyard (for this a photo ID will be necessary), as tickets sell out, be there at 9am.
