Wrong deck landings still happen at a decent rate, I’d guess at least one per year. Some make the headlines, many don’t. The AAIB get involved as it’s normally classed as a serious incident in their terms, at least initially until investigated.
Normally a good test of an operator’s just culture. Many reasons for it to happen, many human factors related, but often organisational too. Some days it all lines up and nothing in the world can break in to convince you that it’s not the right deck. Feel for the crew. An unhappy place to be.
