When Charles Fend announces the Fend 100 aircraft, the world's first fully autonomous commercial airliner, he is praised for being a pioneer in aviation history. The Fend 100 will bring a new dawn of commercial flying to the world. One where human pilots are replaced by AI machines that will navigate over 100,000 flights per day. The first flight is a celebratory spectacle - the Fend headquarters crowded with news teams, technology lovers, and aviation enthusiasts. The atmosphere is jovial, and everyone is eager to celebrate.

Until something goes terribly wrong.

The Fend 100 suddenly begins an uncommanded descent over the Atlantic, and neither the engineers on the ground nor the test pilots aboard can override the controls....

But who is responsible?

Is it the wealthy ex-KGB agent, Pavel Morozov, who has shown up from a past Charles had long-forgotten?

Or was it Charles' son, Max - on the run from the FBI after he was accused of sending Fend Aerospace corporate secrets to a criminal enterprise?

And just who is Max Fend?

Is he the man that the media makes him out to be - the wild playboy son of an aerospace tycoon? Or is he what the FBI suspects - an international criminal, mixed up in a Russian espionage game? And why is there a top secret personnel file on him that even his FBI investigator isn't allowed to see?

Glidepath is a race to uncover the truth, before it comes crashing down from above....
