It is not that I have not heard that before, but in researching your query, I came across information that calls that assertion into question. In fact, the Wikipedia entry on the subject has conflicting info on the same page. First, it states:

The flag which had hung in the Mission Operations Control Room (MOCR) in the Mission Control Center through the prior Apollo landings was flown to the Moon on the final mission, Apollo 17. This flag measured 20% wider and taller than the others requiring a 6-foot (1.8 m) long horizontal pole. Gene Cernan and Harrison Schmitt carried a second, identical flag to the Moon and back, and presented it to flight controller Gene Kranz after the flight, to replace the one left on the Moon.

The flag that we took to deploy was the one that had hung on the wall of the Mission Control Center during all the landing missions. And we also had another flag, which we brought back to replace the one that we deployed at Taurus-Littrow.

Referring to the Apollo mission press kits, regarding each flight's flag kit, only the Apollo 11 entry mentions having "two large American flags" in addition to the 4-by-6-inch smaller flags common to the other missions. There is nothing said, though, that these larger flags were prepared as was the one that was deployed on the surface.

Johnson Space Center displays a large American flag that was flown on Apollo 11 outside the Teague Auditorium in Building 2. It was originally presented by the crew to Robert Gilruth, if I recall correctly.

And here is a photo of Cernan and Harrison Schmitt presenting the flag they flew to replace the one they took from Mission Control to Gene Kranz in December 1973. The NASA caption for the photo makes no mention of Apollo 11, either.

Two of the three Apollo 17 crewmen join in commemoration of their historical lunar landing mission of one year ago by presenting to flight controllers in Mission Control Center (MCC) the U.S. flag which flew with them to the moon. Astronauts Eugene A. Cernan, center, Apollo 17 commander, and Harrison H. Schmitt, right, lunar module pilot, are shown with Eugene F. Kranz, who accepted the flag on behalf of all the flight controllers during special ceremonies in the Mission Operations Control Room (MOCR) of MCC during the third manned Skylab mission. Kranz is chief of the Flight Control Division of the Flight Operations Directorate at JSC.

The flag that Apollo 17 left on the Moon was somewhat unique. It was a flag that went to the Moon and back on Apollo 11, hung on the wall in Mission Control until it made a return trip to the Moon, this time to stay. An identical flag made a round trip on Apollo 17 and now hangs in Mission Control.

First, from the Apollo Lunar Surface Journal, Harrison Schmitt's words after deploying the flag on the moon:

Houston, I don't know how many of you are aware of this, but this flag has flown in the MOCR (Mission Operations Control Room at the Johnson Space Center in Houston) since Apollo 11. And we very proudly deploy it on the Moon, to stay for as long as it can, in honor of all those people who have worked so hard to put us here and to put every other crew here and to make the country, United States, and mankind, something different than it was.

Apollo 17 Flag to Fly in MOCR

On December 11, 1972, Apollo 17 touched down on Taurus-Littrow to finalize manned lunar landings.

Commemorating the event, Apollo 17 commander Eugene Cernan and lunar module pilot, Jack Schmitt last Tuesday presented a U.S. flag which flew aboard the Apollo spacecraft, the "America," to mission controllers and "all the people at JSC who supported the operation."

The ceremony took place in the Mission Control Center at approximately 1:54 p.m.

"The real significance of this flag," Cernan stated, "is manifested in its own history, but to us, the fact that we had the opportunity to carry it, sort of represents the dedication and effort and the courage and self-sacrifice of so many of you people at the Center who made the mission possible."

Schmitt added, "I think all of you remember what I said when we deployed the flag similar to this on the Moon, that was the flag that flew in the MOCR during Apollo 11 through Apollo 16 and its up there, not only representing the country, but everyone involved in Apollo through the years. This flag went to the same place, but comes back to fly in the MOCR and I hope you'll let it fly here as long as we're flying in space."

Eugene Kranz, Deputy Director of Flight Operations, accepted the flag on behalf of the Center.

"The flag shall always stand in the Mission Control Center," Kranz stated, "and when we look at it, we'll think that dedication to the job, self-sacrifice, attention to detail and craftsmanship are what we need to keep this country great."

Schmitt said his idea was to take the flag that was in Mission Control through Apollo 16 and put it on the Moon. He added it may have been the Apollo 11 backup flag, but he didn't recall that part of it. He also said they took another flag to the Moon and returned it to MOCR.

Another one of the Apollo MOCR alumni members recalled Gene Cernan telling him that, "We took two flags to the moon. The flag we placed on the moon was the backup flag for Apollo 11." This is the reason I always believed the story was true.

This is probably the Apollo 17 flown flag seen in MOCR-1 during the ASTP mission.

Might this be the same flag that was in the MOCR from Apollo 12 to Apollo 16, and later deployed at the Apollo 17 landing site? I'm thinking maybe yes.

This photo has no caption, but shows the Left Hand Side Stowage Compartment (LHSSC) with a FLAG stowage location above the PPK stowage location.

I believe a summary is in order. Apollo 11 flew two flags to the moon, both were purchased "at the last moment" and were Annin & Co. all-nylon 2x3ft flags.

• Flag A was left on the moon and fell over when Eagle's ascent engine blasted off.

• Flag B returned to Earth and was presented to Robert Gilruth and resides in a display case.

• A larger flag (C) was displayed in the Control Room throughout the Apollo 12 to 16 flights.

• Flag C was left on the moon.

• Flag D was returned to Earth and now lives in the Control Room as a replacement for flag C.

• Apollo 11 deployed a 3 by 5 foot flag on the moon. Only one such flag of that size was aboard the mission.

  Apollo 11 also flew a smaller 2 by 3 foot flag, which was presented post-flight to Robert Gilruth (and remains on display at Johnson Space Center today).

• Apollo 12 through Apollo 16 deployed similar 3 by 5 foot flags on the moon.

  During those flights, a 6-foot-wide flag was on display at the front of the Mission Operations Control Room in Mission Control, the same flag that had stood there during the Apollo 11 mission.

• Apollo 17 flew the 6-foot-wide flag that hung in Mission Control and deployed it on the moon.

  Apollo 17 also flew a 3 by 5 foot flag, which was returned to Earth and presented to the flight controllers to display in Mission Control. It remains in the now restored MOCR-2, the Historic Apollo Mission Control Room.

That said, it is not clear if the nylon strips were removed from the other large flags flown aboard the command and lunar module. I have yet to be able to find a clear image of the Gilruth flag from the time of the 1969 presentation, and then there are the two flags that two 5 by 8 foot flags that were first flown over the U.S. Capitol before flying aboard Apollo 11. As this photo shows from the U.S. Senate collection, the nylon strip is present there, too.
