I think some carriers scan in the image of each passenger's passport for each flight to help any unfortunate in-air misplacing of docs. I recall one of the telly Airport-like programmes mentioning this in the past.

Can any ACARS expert state whether previous flights of MH370 would have had confirmed ACARS tx/rx of regular information, I.e positions at a given location? Is it so that ACARS connects to a series of downlink stations and whichever answers first establishes the connection gets the message (removing the out of range issue?).

As it seems many hobbyists routinely grab ACARS transmissions, should it be odd that this flight's wasn't. I presume ACARS should have redundant eqpt inboard (I understand there can be several comms paths). Google brought up this link (about 9/11 and some controversial claims, but if one focuses only on the technical side) shouldn't it imply that MH would have received many 'no connection' responses to any ACARS messages it might have originated? After t/o would they proactively originate many msgs on a typical flight? http://911woodybox.********.fi/2012/...s-uplinks.html
