This plane is worth $250,000,000. Why not a straight up theft? Fly the plane somewhere remote. Offload pax (kill them?) and refuel. Fly away and sell the plane or part it out.
Complex, yes but a big payday.
Who would you sell it to and what makes you think you can trust them?
The biggest drawback in entering into a life of crime is that your business associates are very untrustworthy.
“Fly away and sell the plane or part it out”
No. Planes are bought/sold based on their serial numbers. Logbooks are included with the purchase. The new buyer would need to have proof of no liens, so they would check the serial number against registration for liens.
As regards to parts, similar story. The parts would need to be yellow tagged to be serviceable. Their history would need to be traced. That’s especially true of the engines.
