Ethan Shaw, 34, a senior maintenance engineer, keeps Northwind's aircraft airworthy; Captain Claire Bennett, 31, is the partner he quietly protects. When Ethan saves a diverted flight, Claire takes the credit and flight attendant Ryan frames him with falsified records, costing him his job. Ethan rebuilds his career at Port Amber. Investigators clear his name; Claire realises what she lost, but Ethan, now Director of Maintenance, refuses her second chance and moves on.
