And surely, if they just wanted a plane, there would be easier ways of getting it than kidnapping 200+ civilians from multiple countries.
Maybe not. If it is the pilots who are responsible, the easiest thing for them is to steal one of the planes that they know how to fly and can access easily from an airport they are fully authorized to use. Otherwise, how easy is it to get a plane? Especially one that can go long distances if that was the plan all along?
As for the passengers, collateral damage. If they are on some mission that they believe in, 200 people is nothing - and in fact necessary as part of the ruse of obtaining a big plane.
And here's a thought - maybe the pilots were actually
delivering the plane to someone else, so they are either in it because they believe in some cause, or they are being paid to deliver it. They land/deliver the plane, take their money and disappear, and they're out of it. Whoever bought the plane now has the issue of dealing with the passengers (and any additional crew not in on it). Next job, deal with the plane.
True, to retrofit the plane for private use and cover up it's previous identity is likely a big job - or is it? If they people who bought it paid a couple of pilots to steal it, maybe they have other people who can basically chop shop it. Or, and this is a scary thought, maybe the intention is for the plane to be used only once, so hiding its identity doesn't matter because the intention is to destroy it during whatever it's next use is. Another guess, maybe at least one of the passengers was in on it to keep an eye on the passengers, and perhaps even on the pilots if indeed they were being paid to do this.
This is something I haven't seen much of in the news coverage -
why? We assume hijackers are making a political statement/act of terror, or doing it for some sort of ransom, so they'd have to go public. Now that the focus is on the pilots, all the analysis I'm seeing is focused on
how they could have pulled it off - not
why. I guess without knowing where they were headed it's hard to guess their motivation, but at the same time, surely trying to figure out that motivation might tell us where they went.
