President Biden reportedly proposed that the intruder be shot down , but the Pentagon opposed this action, citing the risk of civilian casualties. In fact, bringing down this type of balloon may be extremely difficult, as it is likely to be highly resistant to the available weapons. It may look fragile, but the sheer size and construction of a stratospheric balloon makes it all but invulnerable. There is also the problem of getting to it. Such balloons ride high in the stratosphere , far above the airliners. They do this to take advantage of the change in wind direction with altitude to steer themselves to where they are needed like sailing ships, then circling above a point of interest. The U.S. military has its own stratospheric spy … [Read more...] about Busting That Chinese Spy Balloon Is Harder Than You Think (Updated: ‘Well That Was Easy’)

Share to Twitter Share to Linkedin The U.S. airline industry has set an ambitious goal to be net carbon neutral by 2050. To some this may seem like a long way off, but consider this is an industry worldwide that was built on using fossil fuels. Given the long lead time and risk to develop new aircraft, 2050 seems like it’s right around the corner. The two most popular commercial planes in the world, the Boeing 737 family and the Airbus A320 family, first took to the skies 56 and 36 years ago, respectively. The newer models are of course more efficient than these first models, but the underlying engineering for both planes is decades old. Sustainable aircraft fuel, or SAF, is one encouraging development for a more sustainable airline future. SAF uses fossil fuel by-products or plant based sources to create fuel for existing aircraft engines. With enough SAF, world airlines could become almost immediately net carbon neutral because their energy needs would no … [Read more...] about The Aviation Industry Is Investing In Sustainable Fuel, But More Is Needed
