I remember seeing that for the first time way back when OSHA was started, and it was very appropriate back then. That said, after spending over 35 years in aviation, I think it would be more appropriate today to relabel it, "NTSB Solution to Safe Cow-Person Activities." As I eventually determined, the NTSB always tries to drive their subordinate department, the FAA, into imposing ever more stringent rules on aircraft design to the point where, due to weight increase, the aircraft can't get airborne. Also, those additions balloon up manufacturing cost, whereby no customer can afford it, and, due to the subsequent loss of fuel economy, few customers could afford to operate it. Hence, the NTSB conclusion is proclaimed to the world, "NTSB Drastically Improves Aircraft Safety!" True, BUT, their aircraft can't fly, no one can afford to buy it, much less operate it, ahh but yes, theirs is the safest aircraft in the world! /s
