"Business Matters: 2.5m Children Homeless in US 18 Nov 14

Tue, 18 Nov 14

New figures show 1 in every 30 children is homeless in the United States. Dr Carmela DeCandia from the National Center on Family Homelessness describes the scale of the problem and explains why the number is often under-reported. We also speak to the BBC's Rob Cameron in Prague where the president of the Czech Republic has been pelted with eggs by protesters at a ceremony to mark the 25th anniversary of the Velvet Revolution. As Airbus files a patent claim for a revolutionary airplane design, we hear from Tom Irvine, formerly at NASA and now at the American Institute of Aeronautics and Astronautics about why there are so many thousands of speculative applications. The BBC's Rahul Tandon joins us from Calcutta to talk about Narendra Modi's 'rock star' welcome during his tour of Australia. We'll also be joined throughout the programme by two guests on opposite sides of the Pacific - David Kuo in Singapore and Cecily McMillan in New York City.
