"

The pilot had no choice. He went through the plane's airlock and jumped,
helped by a hearty boost from Jonner. His parachute blossomed out as he
drifted down toward the green Syrtis Major Lowland. Jonner didn't worry
about him. He knew the pilot's helmet radio would reach Marsport and a
helicopter would rescue him shortly.

"I don't know what you're trying to do, Jonner," said Deveet
apprehensively over his spacehelmet radio. "But whatever it is, you'd
better do it fast. They'll have every plane on Mars looking for us in
half an hour."

"Let 'em look, and keep quiet a while," retorted Jonner. "I've got some
figuring to do."

He put the plane on automatic, took off the spacesuit handhooks and
scribbled figures on a scrap of paper. He tuned in the plane's radio and
called Qoqol on Phobos. They talked to each other briefly in Martian.

The darker green line of a canal crossed the green lowland below them.

"Good, there's Drosinas," muttered Jonner. "Let's see, time 1424 hours,
speed 660 miles an hour...."

Jonner boosted the jets a bit and watched the terrain.

"By Saturn, I almost overran it!" he exclaimed. "Deveet, smash out those
ports."

"Break out the ports?" repeated Deveet. "That'll depressurize the
cabin!"

"That's right. So you'd better be sure your spacesuit's secure."

Obviously puzzled, Deveet strode up and down the cabin, knocking out its
six windows with the handhooks of his spacesuit. Jonner maneuvered the
plane gently, and set it on automatic. He got out of the pilot's seat
and strode to the right front port.

Reaching through the broken window, he pulled in a section of cable that
was trailing alongside. While the baffled Deveet watched, he reeled it
in until he brought up the end of it, to which was attached a
fish-shaped finned metal missile.

Jonner carried the cable end and the attached missile across the cabin
and tossed it out the broken front port on the other side, swinging it
so that the 700-mile-an-hour slipstream snapped it back in through the
rearmost port like a bullet.

"Pick it up and pass it out the right rear port," he commanded. "We'll
have to pass it to each other from port to port. The slipstream won't
let us swing it forward and through."

In a few moments, the two of them had worked the missile and the cable
end to the right front port and in through it. Originating above the
plane, it now made a loop through the four open ports. Jonner untied the
missile and ti
