At what point did you stop seeing it. Did it just disappear? I suppose what I am getting at it, could it have been some practical joke involving a remote controlled bit of gadgetry (I have an artist friend who used to do movie special effects, including remote controlled sculpture, and it's the kind of thing he would do). Could someone then just have picked it up and pocketed it? I realise it was practically in full sight of you the whole time, from the description. Could someone have been reaching through from under the seat behind? From the description, it really does sound bizarre.
