London Metal exchange is getting serious about child labour and conflict
London (CNN Business)The world’s biggest metal exchange is changing its rules to combat child labor, money laundering, bribery and corruption.
The London Metal Exchange will require producers that operate in high-risk and conflict zones to demonstrate that their products are responsibly sourced by 2022.
It’s a major policy shift for the 142-year-old exchange, which until now certified metals for trade only by evaluating qualities such as their shape, weight and chemical composition. Now it’s trying to ensure that the metal that ends up in cars or electronic devices is ethically sourced.
World’s Largest Airplane Makes First Successful Test Flight
AIWA! NO!||A notable aviation record has been broken with the maiden flight of what is now the world’s largest aircraft – the Scaled Composites-built twin-fuselageStratolaunch, whose 117m (385ft) wingspan outstrips even the 97.5m of the Hughes H-4 Hercules flying boat, better known as the Spruce Goose.
The biggest aircraft in the world took off for its first flight and, most importantly, successfully completed it on 13 April 2019. It is the Stratolaunch Roc, the carbon-composite plane built by Stratolaunch Systems, founded in 2011 by Paul G. Allen.
The plane with “a dual fuselage design and wingspan greater than the length of an American football field”, achieved its historic milestone over the Mojave Desert in California in a flight which lasted for 2.5 hours at altitudes up to 17,000 feet.
