US plane maker Boeing has replaced its chief executive Dennis Muilenburg in the wake of two deadly 737 Max crashes and the plane's subsequent grounding. We speak to Scott Hamilton, an aviation industry consultant with Leeham news and analysis in Seattle. Plus, UK defence and aerospace company Cobham has been bought by a US private equity firm in a $5bn deal that could test the new government's tolerance of foreign takeovers. Also in the programme, how green is the internet? We examine the energy consumed powering the web. And if you're looking for a last minute Christmas bargain, a small newspaper business in Alaska is looking to be snapped up. The asking price? Free - we find out why.

All this and more discussed with guests Erin Delmore, a political reporter in New York, and journalist Jyoti Malhotra in Delhi.
