Inspired by a page linked to a page linked to in this thread and this Wikipedia list of Cold War pilot defections.
Have there been many cases where someone was trying to defect and got themselves shot to pieces, not by the country he or she was fleeing, but by the country they were fleeing to? Most of those on the wikipedia list got to their destination or crashed trying.
Also did those who were successful and weren’t being coaxed by the intelligence services of the West cause a shit storm in the receiving country? Did anyone arrive unannounced? Victor Belenko got his MiG 25 into Japan flying under their radar, did heads roll in the military afterwards.
