"Private aircraft can't simply file a flight plan to Antarctica."
"They can't?"
"No."
"The continent is governed by international treaty. Flights are heavily regulated. Without government authorization, an approved research mission, military coordination, or a recognized logistical operator, you won't receive clearance."
He let that sink in. "If you're planning to fly there legally, you'll need institutional backing."
"And if I'm not?"
Another brief silence. "Then you'll need a route that avoids needing permission."
Stan nodded to himself. "I understand."
"I'll handle the aircraft."
"And I'll handle everything else."
"Exactly." Grayson exhaled.
"Stan."
"Yes?"
"I don't know what you've gotten yourself involved in."
His voice was quieter now. "But whatever this is, be careful."
"I will."
The call ended.
Stan set the phone down. Grayson had almost certainly become more suspicious of him.
