No, you were aboard the Collings Foundation's B-17, "Nine 'O Nine." Those two planes tour all the time together. I've been aboard them too.
That one in the pics is, I belive, the original "Memphis Belle." Been in storage for decades.

After the war, the Memphis Belle was saved from reclamation at Altus Air Force Base, where she had been consigned since 1 August 1945, by the efforts of the mayor of Memphis, Walter Chandler, and the city bought the B-17 for $350. She was flown to Memphis in July 1946 and stored until the summer of 1949 when she was placed on display at the National Guard armory. She sat out-of-doors into the 1980s, slowly deteriorating due to weather and vandalism. Souvenir hunters removed almost all of the interior components. Eventually no instruments were left in the cockpit, and virtually every removable piece of the aircraft's interior had been scavenged, often severing the aircraft's wiring and control cables in the process.

I believe I have been aboard this aircraft, if it's the same one that toured with the B-24 All American
