Continuity achieved

What do you do when your star has had enough? Those watching seried 4 of Airwolf [Legend, 19:00] have found out that you dump the star, Stringfellow Hawk, for his brother, St. John,  who has been released from illegal captivity.
    But as it’s the helicopter that’s the real star, no worries.
    The old bloke in charge of Santini Air has also gone, and there’s a new female helper. And a new bloke sidekick.
    Business as before with new faces.
