The Amazon Mk23M-1 Hybrid Delivery Drone is moved after arriving as a new addition to the collection at the Steven F. Udvar-Hazy Center.
The National Air and Space Museum is known worldwide for its collection of rare and historically significant aircraft and spacecraft, as well as its thousands of related smaller artifacts and archival materials. This includes more milestone first or one-of-a-kind aircraft than any other museum. These collections are cared for by a professional team of museum specialists, conservators, and archivists. Some highlights of the team’s work in 2018 include:
Object Collections
Exhibits Specialist Adam Bradshaw, worked with others on the team to take down and put away the white beta cloth lunar spacesuit worn by Neil Armstrong on Apollo 11 mission following a photo shoot in the “Emil Buehler Conservation Laboratory, Steven F. Udvar-Hazy Center. The suit will go back on public display in 2019 as part of celebrations of the Apollo 11 50th anniversary.
Archival Collections

Ideas That Defy – Innovation in conservation
Innovation is not just the heart of stories the museum tells, but part of the work it does. The conservation team is a prime example. While they often use tried-and-true techniques to conserve and restore our amazing collections, the one-of-a-kind nature of so many artifacts means they often have to be as creative as the people who built these magnificent flying machines.
That is the case with two treatments they devised to prepare Flak-Bait for exhibition. Flak-Bait is the Martin B-26B-25-MA that survived 207 operational missions over Europe, more than any other American aircraft during World War II.
While enemy fire may have pierced the exterior many times during battle, the enemy of the interior lining fabric was moths. By the time it reached the museum, they’d begun feasting on the wool lining, badly damaging it. Utilizing modern cutting tools that weren’t available when Flak-Bait flew, conservators tried something new. “We were able to save and ‘visually reintegrate’ most of the original fabric with the use of laser-cut replacement fabric samples,” said Engen Conservation Fellow, Meghann Girard. “The samples are from a similar pool-table cloth we found that we had custom dyed to match the original fabric. Losses in the original fabric were traced, scanned and laser-cut replacements were created and sewn into the areas of moth damage.”
The control surfaces (rudder, ailerons, elevators) were badly deteriorated due to natural degradation of the doped fabric. It shrinks and becomes brittle over time, causing tears and making it prone to breaking under the slightest pressure. The traditional solution is to cut off the damaged sections and completely replace them with new materials.
“On Flak-Bait, these components also exhibited combat damages with in-the-field repairs and patches. We really wanted to save this important evidence of the aircraft’s operational history,” said Conservator, Lauren Horelick. Their innovative solution drew on the lessons learned from how fine art is conserved. “We performed a lining technique to provide the structural support the doped fabric needed. This allowed us to preserve the original fabric with the combat damages and we were able to fill and blend the more modern damages caused by time,” Horelick added.
Thinking and working creatively will help the team reach its goal to preserve the aircraft to look as it did in 1945, with all its wear and tear from two years in combat.
As a leader in aircraft conservation, the National Air and Space Museum wants to share our innovations with others and in support of this, team members recently presented these techniques at conferences and through a coming peer-reviewed article, helping others in the field preserve important parts of the nation’s collective air and space legacy.
