Think you'd be allowed on an airplane with this?

I doubt it.  Looks like a bazooka.  I tried to get on the plane with a couple of castings, a U-Joint assembly and a steering knuckle.  They were really concerned about the U-joint assembly as it looked like an Uzi - that weighed about 20lbs.  This was pre 9/11.
 
So, I suppose this is a case of "if you have to ask how much it is..."

[bdann]

Don't know how much it is, likely $10,000+, maybe even considerably more than that.  f/2.8 at 500mm is quite a feat.  It weighs 40lbs, and operates under it's own power.

...and operates under it's own power. 

It should move under it's own power.

I'm not 1000% convinced that thing's for real.  They "introduced" it last March at the big PMA convention in Vegas, even had a mock up, but it  hadn't been seen again until this year's PMA, which is going on now.  I'm wondering if Sigma's trying to give the CaNikon deisgn engineers a bad case of  .

 Operates under it's own power?.....I thought it was a lens, what else does that device do?...push a button and throws you sandwiches?

Soooo I guess you put batteries in a lens.  Or maybe it has a thermo-nuclear power plant built in.

It needs it's own power supply for the AF;  takes a lot of juice to move that much heavy glass around.  Since most new cameras come equipped with an over abundance of electronic tricks (movie mode, GPS, micorwave oven, sauna) they don't want to run down the main battery.

Got a picture of that? I cannot imagine how a U-joint would resemble an Uzi (and I have hands-on experience with both).

Back in 1979(?) I was flying to Dallas to attend a continuing education course in orthodontics.  I had to take a number of things with me:  ortho wire in various sizes/shapes, pliers, brackets, models of patient's teeth, appliances made of acrylic, etc.  All this showed up on an xray scan.  They didn't pull a gun on me, but they came close.

models of patient's teeth

Ever considered putting several of those wind-up chattering teeth in your carry-on for entertainment purposes? That would make quite a sight on the xray.
