You could never accuse Rex and Melissa Pemberton of having a dull marriage.
They met while base jumping in Australia.
Then they declared their love for each other as Melissa hung precariously from a snagged parachute, halfway down a gorge.
Their latest trick involves Rex soaring through the sky wearing a wing suit, reaching speeds of 160 kilometres per hour while Melissa, in a stunt plane, performs breath taking loops around him.
It's man versus machine for this husband and wife.
They vow to love, honour and avoid collision.
Trust is everything in this marriage.
