London City Airport's getting a new control tower: but it's just going to be a large mast with 14 high-definition cameras on it. The actual tower will be 80 miles away, in the headquarters of NATS near Swanwick. It feels questionable: but is it? Thanks to all the team at NATS: you can find out more about the new tower here: https://www.nats.aero/services/airports/digital-remote-towers/ Edited by Michelle Martin, @mrsmmartin London camera by Matt Gray, http://mattg.co.uk I'm at http://tomscott

In the Quadratestadt of Mannheim, Germany, the streets aren't named: instead, the blocks are. It's an exception to a rule that most people don't even think about — especially not mapping companies. (Thanks to João Correia for sending me this idea back in 2015!)

In Weeki Wachee Springs State Park, Florida, there's a mermaid show -- and there has been for 70 years. It's one of the United States' oldest roadside attractions, and it still does three shows a day. At least, provided the local wildlife doesn't get in the way.

US Car Number 1, the Ferdinand Magellan, sits in the Gold Coast Railway Museum in Miami. It's 120 tonnes of bulletproof, armoured railcar: a train carriage designed to move the President of the United States around the country in safety and style. At least, it was, until other transport came along to do a better job. Thanks to all the team at the Gold Coast Railroad Museum: they're at http://www.gcrm.org/, or on Facebook at https://www.facebook.com/GoldCoastRailroad/ ! [looks like their main si

In Quebec, Canada, there's a town called Asbestos. It's an alarming name, one that conjures up images of lung disease and mesothelioma. So now that the town's asbestos mine, once the largest asbestos mine in the world, has closed... why haven't they changed the name? Dr Jessica van Horssen's book, "A Town Called Asbestos", was invaluable for my research. Its ISBN is 9780774828420, and it can be ordered from most libraries and bookstores.

Rue Canusa (or Canusa Avenue) is a street that's split in two by a border: the northern part is in Stanstead, Canada, and the southern part is in Derby Line, USA — and border crossings here aren't as easy as they used to be.

Thanks to Betty from Articulations! Go see her video on the ISO Standard Exit Sign here: https://youtu.be/i5uSlAw8U9s - and pull down this description for links to all her sources. The St Lawrence Burns were a series of deliberate fires in the soon-to-be-demolished village of Aultsville, Ontario, which was due to be flooded to make way for the St Lawrence Seaway. The results changed the way buildings are constructed around the world, and saved lives. SOURCES: Setting Fires for Science (1958):

Giant Mine sits near Yellowknife, in the Northwest Territories of Canada. Once it was a productive gold mine, but after the gold ran out, the mining company went bankrupt and left the government to clean up the mess: enough arsenic trioxide dust to kill everyone on Earth. The solution: freezing it, at least for now. Thanks to all the team at the Giant Mine Remediation Project!

Until recently, Canada didn't have a road link to the Arctic Ocean. But last year, the all-weather Inuvik-Tuktoyaktuk Highway opened, which meant that finally the country was connected "from sea to sea to sea". I set out to drive it, but it didn't quite go how I planned.

In the far north of Canada sit the DEW Line stations: "Distant Early Warning". Built in the 1950s, these were the sites that would have sounded the alarm if the Soviet Union ever attacked North America. Or at least, they were until they went obsolete just a few years later.

Over on the RAF Starrship channel, I'm talking about the history of radar: https://youtu.be/VDC_RCh0ws8 - but over here, we're testing a 90-year-old piece of technology that was meant to be part of Britain's air defence. The Sound Mirrors, on Romney Marsh, were built in the late 1920s as a way to amplify the sound from aircraft engines over the English Channel. We're flying a bit closer than that, with a drone.

The White Horse, in Uffington, is one of the oldest surviving works of art in Britain: carved into a hillside in Oxfordshire 3,000 years ago. Every year, it's rechalked by volunteers co-ordinated through the National Trust, a line of maintenance going back to before England had written history. Thanks to all the National Trust team! If you're free over the August bank holiday and fancy helping out, here's the link! https://www.nationaltrust.org.uk/events/9220f3c2-d50f-4a9e-9063-8d9346ed5da9/pag

Technically, the Inchindown oil tanks in Invergordon, Scotland, have the world's longest reverberation, but that makes a much worse title. We tested them with a loud noise and some very sensitive microphones.

In a field near Elberton, Georgia, USA, sit a set of mysterious standing stones: mysterious not because they're ancient, but because they were funded by someone anonymous in 1980, perhaps as a message to any survivors of the end of the world.

Some American cities use buses, or trams, or trains. Peachtree City, Georgia, has a different solution: it's not quite public transit, but a hundred miles of golf cart tracks helps to keep cars off the road.

The tourist guides promote it as Georgia's Little Grand Canyon: but this is a scar on the Earth, caused by humans either not understanding or not caring about geology. Is it natural? Or man-made?
