Could be. During the Cold War, armed "navigators" were assigned to Aeroflot's and other Soviet-bloc flag carriers' flights. These (trustworthy) commissars were empowered by the Politburo, KGB, or some other CIA/DHS-equivalent state agency to take whatever action they saw fit, included killing the pilot(s), to "safeguard" the flight. They weren't pilots a far as I know, though they may have been given some minimal flight training. I don't know. Those I've asked were reluctant to engage in any conversation, and the pilots usually answered with a look I was expected to understand. I didn't. Can't recall now, but I believe on the TU-134 these "navigators" didn't have a seat. They strapped themselves standing up into a 5-point harness anchored to the cockpit access aisle bulkhead for takeoffs and landings.
