This from an experienced pilot starting with a new airline several years ago. What walking around blindfolded and holding hands has to do with flight safety, I simply don't know. You tell me.
"I'll never forget doing that 2 day CRM course. It was a total farce. The last exercise (boxes needed to be ticked) involved all 20 of us being blind-folded - the objective to group hug based on being given a silent, personal number. No one was allowed to speak their number, the theory being we would all eventually link up (arms on shoulders) 1 through to 20. The course teacher was a former flight attendant".
