If the Bad Actor was a gummint needing a delivery system then they’d simply BUY it —would arouse less suspicion.
So this MUST be some kind of insurgent group without access to a legit tax base.
So they stole it.
KL to Beijing = 2700 miles straight-line distance.
Round that distance to 3,000, then add 20% for headwinds and air-traffic delays at destination.
So she was prolly loaded with fuel permitting a range of 3,600 miles or so...? A pro pilot could say more.
So their destination or a landing/re-fuel location is within 3,600 miles of KL.
THIS IS SO WEIRD!
This would require a State to coordinate the landing and refueling. Plus they then can claim we didn’t do it when the bomb goes off. No one will want the retaliatory strike to hit them.
