For many years there were free gifts for the pax on every flight and I recall the vast numbers that were left behind and merely binned.
I was fortunate to travel to Andrews Air Force base on the SSC when we took John Major across to meet whoever was president at the time. We parked between a number of fighters and were swamped with US air force staff that wanted a look around and the engineering Manager was in his element lecturing about the a/c's many advanced systems.
Upon departure we had battery issues and asked for a ground power unit to assist. The USAF ground crew returned with a hand held unit for fighter a/c and seemingly had nothing else to offer us. We did get started but the crew were expecting the worse.
I also recall being in Almaty and was told that the TU144 ended up doing freight services between Moscow and Almaty at the end of its brief life. There were 2 TU's present both in poor condition.
