When the cruise ship Viking Sky sent out a mayday call in 2019, the Sikorsky S-92 helicopter flew to the rescue. Despite 25-foot waves and screaming winds, crews were able to pluck 479 stranded vacationers off the embattled liner before it limped back to port. It seems there’s little that this workhorse helicopter can’t do: S-92s ferry oil workers to offshore rigs, help patrol national borders and will soon shuttle the American president as Marine One.
