Helicopter to block mobile calls in Sydney
Link: Mobile blocking helicopter to trail Bush in Sydney | The Register
Interesting news has emerged this afternoon about a plan to block mobile phone calls during US President George W. Bush’s trip to Australia.
Conjecture around the phone-jamming helicopter has arisen as a result of its appearance in attendance on Mr Bush at the 2005 APEC summit in South Korea. Reporters covering the conference said that a Black Hawk chopper would shadow the presidential motorcade, and as it passed overhead mobile phones would lose touch with the local network.
More at the Sydney Daily Telegraph.
What a load of rubbish, by announcing it to the world they are simply advising any would-be assassins that cellphones aren’t a viable method of detonation and to use something else.
What they are really saying is that George Bush is more important than your phone calls.
George Bush is more important than your ability to call the emergency services.
I, personally, disagree.

So instead, you just set your bomb to detonate or gas canister to vent when a decent amount of wideband noise was detected. Much cheaper/easier to do.
Or, install a ‘prat in an SUV’ detector.
