One of the many oddities about traveling to and within Russia is the strange behavior by passengers. On our first trip to Russia, several of the passengers clapped when we landed in Moscow. Thinking it odd, we promptly forgot about it in the hustle to get our bags, get through customs and to find our ride.
But, it happened again when we landed in Krasnoyarsk and again when we landed back in Moscow. We never had the nerve to ask anyone why that was the case, in part because we didn't really want to know if it was something to truly celebrate. We were in a large plane, afterall!
We returned to "normal" landing behavior upon our arrival in the U. S. No clapping.
Maybe on our pending return trip we'll ask someone about the clapping, if it happens again!
