In 1967 I flew on a Turkish DC-7B from Frankfurt to Vienna. I thoroughly enjoyed the lightly loaded flight. I had three seats all to myself across from the galley, which was also the main cabin entrance, which is behind the wing on the DC-7. I had a nice turkey dinner. After the dinner trays were picked up, a female flight attendant walking by winked at me and walked toward the rear of the cabin. I stood up and looked back there and saw her and a male flight attendant in one of the back rows making out. No passengers were seated back there, so they saw their opportunity.
