DT-1 was the private jet of the Tracy family. It had been built as a means of transport for whenever Daniel or any other member of the family wanted to travel around the world without revealing their cover as International Rescue.

Today, it was Zoë who was taking the jet, being flown to England by Heidi Rowley. DT-1 was kept on Moratoa Island as there wasn't any room in Thunderbird 2's vast hangar anymore. Its place in the hangar had been taken by Thunderbird 6, the old de-Havilland Tiger Moth bi-plane which was only really used as a training aircraft. Heidi took the responsibility of both her duties on Moratoa and flying DT-1 very seriously. Even though she was very happy with her work on the island, she was always pleased when she got the chance to fly Daniel or any of the others to wherever they wanted to go.

Zoë had been dozing in the cabin when Heidi called her over the PA. "We're just approaching the South Coast of England now, Mrs Tracy. Our ETA to Norwich is about twenty-five minutes."

Zoë checked her watch. "Thank you, Heidi," she said, sleepily. "I'd better get myself ready."

It wasn't long before DT-1 was over England crossing over Sussex and Kent before passing over the River Thames into Essex, Suffolk and then finally into Norfolk where they began their final approach to Norwich Airport.

"Norwich Tower, this Private Jet DT-1," Heidi said into her radio headpiece. "Approaching you from the South. Request landing instructions."

"DT-1 this is Norwich Tower," came the reply from a female operator in the airport's control tower. "You are clear for landing on Runway 1-Bravo."

"Roger, Runway 1-Bravo," said Heidi. "Thank you, Norwich." She flicked a few switches on the control panel. "Mrs Tracy, we're about to land at Norwich. Please fasten your safety-belt."

Zoë did so and readied herself for the landing. As she felt the plane descend, she looked out of the window at the clear, blue skies around them. It had been a long time since she'd last been in England, and deep down inside her was a feeling that was making her feel uncomfortable. "Calm down now, Zoë," she said to herself. "I cannot let our guests down. Robert would never approve of that."

There was a soft bump as DT-1 landed on the runway. Zoë felt her stomach churn slightly. Take-offs she never minded, but it was always the landings that she didn't like.

Heidi then taxied the plane through the airport past all the large airliners and other smaller planes to a secure waiting area on the western side near to one of the car parks.

As Zoë disembarked from DT-1, Heidi helped her with her luggage. At the bottom of the stairs was a sleek, black Bugatti Veyron with two smartly-dressed men and a woman standing beside it. The two men hurried forwards and took Zoë's luggage off her and Heidi whilst the woman opened the right-side rear passenger door for Zoë to step inside.

"Thank you for bringing me, Heidi," Zoë said gratefully. "I do hope it hasn't delayed any of your other work for Daniel?"

"Not at all, Mrs Tracy," Heidi said. "Do you want me to call Daniel and let him know you've arrived safely?"

"If you wouldn't mind, yes please," said Zoë. "And tell him that I'll give him and Kerry a call once I'm settled in."

"Of course," said Heidi. "Hope it all goes well. Take care."

Zoë then gave Heidi a little kiss on the cheek. "Thank you, hun," she said and then walked over to the waiting car. "Safe flight home."

Heidi smiled.

"Hello, Mrs Tracy," said the woman. "It's been a long time."

"Good to see you, Wendy," Zoë replied. "It's good to be back."

But as Zoë climbed into the back of the Bugatti, the sickly feeling she'd had on the plane returned. Deep down inside, she really didn't want to be here.

Heidi watched as the car headed off. Then she climbed back into the jet. As she sat herself down in the pilot's seat to make pre-flight checks, she couldn't help but feel a little worried about Zoë. She had noticed that she'd been very quiet during pretty much the whole flight and hoped there was nothing wrong.

Once all the checks were completed, Heidi moved DT-1 into the take-off holding pattern. She had to wait for two planes to lane and one to take-off before she got her turn.

"Private Jet DT-1 from Norwich Tower, you are cleared for take-off," the tower controller said. "Have a good flight."

"Roger, Norwich Tower," Heidi replied. "And thank you."

DT-1 accelerated down the runway and lifted off into the sky once more. Heidi turned the jet round and headed South-West to begin the long journey back to Tracy Island. As she was making the turn, Heidi caught sight of the Bugatti Veyron taking the road towards the coast. "Good luck, Mrs Tracy," she said. "Something tells me you're going to need it."
