The ''Ticonderoga'' delivered the Apollo 16 command module to the [[Naval Air Station North Island|North Island Naval Air Station]], near San Diego, California, on Friday, May 5, 1972. On Monday, May 8, ground service equipment being used to empty the residual toxic reaction control system fuel in the command module tanks exploded in a Naval Air Station hangar. Forty-six people were sent to the hospital for 24 to 48 hours' observation, most suffering from inhalation of toxic fumes. Most seriously injured was a technician who suffered a fractured kneecap when a cart overturned on him. A hole was blown in the hangar roof 250 feet above; about 40 windows in the hangar were shattered. The command module suffered a three-inch gash in one panel.<ref>{{cite news|title=46 injured in Apollo 16 explosion|url=https://news.google.com/newspapers?id=0eUzAAAAIBAJ&pg=1722%2C2797182|access-date=December 2, 2011|agency=[[United Press International]]|newspaper=[[Lodi News-Sentinel]]|date=May 8, 1972|pages=1–[https://news.google.com/newspapers?id=0eUzAAAAIBAJ&pg=6132%2C2805357 2]|archive-date=February 1, 2022|archive-url=https://web.archive.org/web/20220201050639/https://news.google.com/newspapers?id=0eUzAAAAIBAJ&pg=1722%2C2797182|url-status=live}}</ref><ref>{{cite news|title=Apollo blast: 46 hurt|url=https://news.google.com/newspapers?id=03lWAAAAIBAJ&pg=6904%2C1961609|access-date=December 2, 2011|agency=[[Australian Associated Press]]-[[Reuters]]|newspaper=[[The Sydney Morning Herald]]|date=May 9, 1972|page=1|archive-date=December 31, 2020|archive-url=https://web.archive.org/web/20201231213229/https://news.google.com/newspapers?id=03lWAAAAIBAJ&pg=6904%2C1961609|url-status=live}}</ref>

The S-IVB was deliberately crashed into the Moon. However, due to a communication failure before impact the exact location was unknown until January 2016, when it was discovered within [[Mare Insularum]] by the [[Lunar Reconnaissance Orbiter]], approximately {{convert|160|mi|km|abbr=on|order=flip}} southwest of [[Copernicus (lunar crater)|Copernicus Crater]].<ref name="fullsummary" /><ref name=":0">{{cite web|title=Apollo – Current Locations|url=http://nssdc.gsfc.nasa.gov/planetary/lunar/apolloloc.html|publisher=[[NASA]]|access-date=December 2, 2011|archive-date=July 17, 2011|archive-url=https://web.archive.org/web/20110717164926/http://nssdc.gsfc.nasa.gov/planetary/lunar/apolloloc.html|url-status=live}}</ref><ref>{{cite news|url=http://www.space.com/31503-apollo-16-moon-rocket-crash-site-photo.html|title=Moon Mystery Solved!

[[File:Charlie Duke's family portrait left on the surface of the moon.jpg|thumb|left|Duke left a photo of his family on the Moon.]]
Duke left two items on the Moon, both of which he photographed while there. One is a plastic-encased photo portrait of his family. The reverse of the photo is signed by Duke's family and bears this message: "This is the family of Astronaut Duke from Planet Earth. Landed on the Moon, April 1972." The other item was a commemorative medal issued by the United States Air Force, which was celebrating its 25th anniversary in 1972. He took two medals, leaving one on the Moon and donating the other to the [[National Museum of the United States Air Force]] at [[Wright-Patterson Air Force Base]] in Ohio.{{sfn|Swanson 1999|pp=281–282}}

In 2006, shortly after [[Hurricane Ernesto (2006)|Hurricane Ernesto]] affected [[Bath, North Carolina]], eleven-year-old Kevin Schanze discovered a piece of metal debris on the ground near his beach home. Schanze and a friend discovered a "stamp" on the {{convert|36|in|cm|adj=on|order=flip|sp=us}} flat metal sheet, which upon further inspection turned out to be a faded copy of the Apollo 16 mission insignia. NASA later confirmed the object to be a piece of the first stage of the Saturn{{nbsp}}V that had launched Apollo 16 into space. In July 2011, after returning the piece of debris at NASA's request, 16-year-old Schanze was given an all-access tour of the Kennedy Space Center and VIP seating for the launch of [[STS-135]], the final mission of the [[Space Shuttle program]].<ref>{{cite news|title=Durham teen discovers piece of space history, lands VIP seat at final launch |first=Penn |last=Holderness |url=http://www.wncn.com/story/20907836/durham-teen-discovers-piece-of-space-history-lands-vip-seat-at-final-launch |work=[[WNCN]] |publisher=[[Media General|Media General, Inc.]] |date=July 8, 2011|url-status=dead |archive-url=https://web.archive.org/web/20131103020011/http://www.wncn.com/story/20907836/durham-teen-discovers-piece-of-space-history-lands-vip-seat-at-final-launch |archive-date=November 3, 2013 }}</ref>
