No, they won't.[*]

You make colossal assumptions to arrive at your "conclusions", and while *some* of the scenarios you describe _may_ match the reality of what occurred, most are fantasy and supposition, requiring an highly arbitrary set of circumstances to pertain.


[*] They may in the future, under various UK Govt and EU proposals, but that is another matter...

RTFM,

I believe you are confusing the information the networks are already 'archiving', with the information they may in future will be legislated to 'archive' :ok:

You seem to also be confused as to the purpose of 'the scenarios'. They are to describe how text messaging systems work, not what may or may not have happened that morning :ugh:

Agreed.

Where I work (two crew fixed wing ops) CPDLC is used in the Upper Airspace only, and whilst there is a text option it is rarely used, CPDLC is usually only used for send/receive pre-formatted messages to/from ATC.

1) SMS or MMS; no notification of text entry, nothing happens until you press "send". The system is store-and-forward, not instant.

You can request notification of delivery, usually deep in a configuration menu on your phone. This is a network service, so the operator would know, as would you. But hardly anyone uses this.

2) BBM; is a private, IP-based instant messaging system. Messaging is online, and some features like notification of entry are available. The owner of the BES (BlackBerry Enterprise Server) will know; the owner of a BIS (BB Internet Server, the hosted version) may know depending on the terms of agreement between them and RIM.

3) Apple iMessage, WhatsApp, etc: IP-based, usually XMPP messaging. Online and feature-rich. The operator wouldn't know but the owner of the XMPP server might.

Confusion may arise because iMessage provides an integrated view of the SMS and iMessage inboxes, choosing to use iMessage to anyone whose iMessage or other XMPP IM address it knows.

BBC News - Vauxhall helicopter crash 'was preventable'

A fatal helicopter crash in central London might have been avoided if safety concerns raised in a 2005 report had been heeded, some experts warn.
