S1 E4: The Sikorsky S-92 is the ultimate search and rescue helicopter, a high-tech, all-weather machine. The Shetland Coastguard is eagerly awaiting the arrival of one but it's still in a Pennsylvania factory 3,500 miles away. That's too far for a chopper to fly alone, so it's going to need an escort. Enter the Antonov 124, a Cold War warrior with record-breaking cargo capabilities. Antonov is big, but so is the Sikorsky S-92, an eight-ton beast. Can a team of engineers squeeze this $30 million aircraft in and get her to the Shetlands unscathed?
