Ultimately, what really matters isn’t the amount of greenhouse gas emissions; what matters is the higher temperatures and their impact on humans. And on that front, a gas like methane is much worse than carbon dioxide. It drives the temperature up immediately, and by quite a bit. When you...
Radial engines have several advantages for airplanes: They can produce a lot of power. A typical radial engine in a B-17 has nine cylinders, displaces 1,800 cubic inches (29.5 liters) and produces 1,200 Radial engines have a relatively low maximum rpm (rotations per minute) rate, so the...
Depleted uranium is used, for example, in boats and airplanes as ballast. The three properties that make depleted uranium useful in penetrating weapons are its: Density - Depleted uranium is 1.7 times heavier than lead, and 2.4 times heavier than steel. Hardness - If you look at a Web site...
Pick early morning flights.According to Keyes, early morning flights have a higher completion rate due to better flying conditions. Plus, airplanes awaiting early flights are parked at the airport overnight, waiting and ready to go. Avoid checking a bag.A delay or cancellation can be much easie...

Climate impact mitigation pathways Besides the reference scenario where European aviation relies exclusively on fossil jet fuel, we consider two technology options (i.e., mitigation approaches) to reduce aviation’s climate impact. First, CO2removal is performed by Direct Air Capture (DAC) and perman...
