Something else... What?
The question echoed in Smith's mind as he hurried under the shuttle's left wing toward the landing gear. Either Bauer didn't know or he had overlooked the fact that there was another way into the craft other than through the cocoon. Smith stepped up on the tires, then moved onto the landing assembly. He popped open a small hatch, reached inside, and pulled down a handcrank. Fitting one end into a slot, he began turning. Little by little, the much larger hatch detached itself from the orbiter.
Pushing the hatch to one side, Smith climbed into the belly of the payload bay located behind the Spacelab. He found himself crouching next to the get-away canisters where unattended experiments and supplies were stored. In front of them was an oval, submarine-type door--- the back entry to the Spacelab.
Inside the Spacelab, Megan Olson stared in horror as the wheel on the rear door spun faster and faster. Leaning against the sled chair, she felt dizzy and nauseated. Even though she'd been strapped in as securely as possible, the buffeting reentry had been extremely jarring. She felt as though her entire body had been pummeled.
It's not too late. I can still get out of here.
Seizing that thought, she'd climbed out of the sled chair and staggered to the door that connected the lab to the tunnel. But after a few minutes of trying, she realized that either she was too weak or the door was locked from the outside.
Fighting back tears, she had tried desperately to think of another way out. Then she had heard the sounds coming from the get-away section of the payload bay.
Why is Reed coming back? And why that way?
Frantically Megan looked around for something that might serve as a weapon, but found nothing. She heard the hiss of a seal breaking. As the door swung back, she moved to the side, raising both arms over her head. Surprise would be her only defense against Reed.
First a leg appeared, then a pair of arms. As soon as Megan saw the helmet, she started to bring down her arms. Then, in that split second, she realized that it wasn't a space suit, but one designed for biohazard work. She managed to stop her swing just as the figure looked up at her.
"Megan!"
She tried to grab Smith but her gloved hands slipped off his suit. The next instant he was holding her by the shoulders, his helmet bumping hers, their faceplates touching. She couldn't take her eyes off his. She leaned against his shoulder and wept for everything that, only moments ago, seemed to have been snatched away, and was now restored. She pulled back a little so that she could look at him.
"How did you know?"
"They heard you in mission control. Not much got through, but enough so they knew you were alive."
"So you came for me...."
They stared at each other, then Smith said, "Come on. We've got to get out of here."
"But Reed---"
"I know about him," Smith told her. "He was working for Karl Bauer."
"Bauer?"
"He was the man you saw with Reed the night before the launch. Bauer's onboard right now. He came to take the smallpox mutation Reed had created in microgravity. But he's not going to just walk out of here, Megan. He has to destroy all evidence of what happened on this flight."
Then he told her exactly where the shuttle was parked and why, about the holding chamber that was really a giant crematorium.
Megan shook her head. "No, Jon," she said. "He's doing it another way.
"What do you mean?"
Megan pointed to an overhead readout she had noticed a moment ago. "That's the autodestruct sequence, armed and counting down. Once it's been set, it can't be turned off or extended. We have less than four minutes before the shuttle explodes."
Seventy seconds later, Smith and Megan Olson were climbing out of the craft the way Smith had gone in.
Megan shuddered when she looked around the cavernous death chamber. She turned to Smith, who was locking the hatch they had passed through.
"What are you doing?"
"Making sure that no one follows us." He stepped on a tire, then to the ground. "Let's go."
Moving as quickly as their bulky suits permitted, they came around the wing. Megan gasped when she saw the cocoon mated to the shuttle's lower escape hatch and to the cavity in the far wall.
"Is that how we're supposed to get out?"
"It's the only way."
As they approached the cocoon, Smith could see that the hatch to the
