Iain Banks - Dead Air

Ken Nott is a devoutly contrarian vaguely left wing radio shock-jock living in London. After a wedding breakfast people start dropping fruits from a balcony on to a deserted car park ten storeys below, then they start dropping other things; an old TV that doesn't work, a blown loudspeaker, beanbags, other unwanted furniture...Then they get carried away and start dropping things that are still working, while wrecking the rest of the apartment. But mobile phones start ringing and they're told to turn on a TV, because a plane has just crashed into the World Trade Centre.
