The alarm bell goes off!

Suddenly Linda and Adam are startled as the ship's alarm bell goes off.

"What the..." Adam says looking up at the computer screen in the rec room.

"Unidentified ship approaching." the ship's computer voice said in a matter of fact tone.

"There must be a malfucntion." Linda says, "There's nobody out here for millions of miles."

The ship's computer voice continued, "Unidentified ship on a collision course. Time to impact ten minutes."

"We better get to the bridge." Adam suggested as he headed towards the door wearing just his speedos.

Linda quickly followed in just her tiny string bikini and high heels but did manage to grab her robe as she dashed off to the bridge right behind Adam.

What is the mysterious ship?

An alien ship, pirates, a rival company ship, Jerry Steel on a surprise inspection or ???
