(AP) -- To fly, or not? There's no right answer about when it's safe to fly through a cloud of volcanic ash. But it'll be all too obvious if there's a wrong answer, experts say.

Superfast airplanes through super tiny technology

An interdisciplinary team of scientists led by Princeton engineers has been awarded a $3 million grant to study how fuel additives made of tiny particles known as nanocatalysts can help supersonic jets fly faster and make ...

Video: Chemtrails vs. contrails

It's easy to look at the white trail behind a jet aircraft and imagine all manner of chemicals raining down from above. However, airplane contrails are simply what happens when jet engines burn fuel.

The science of jet noise

Daniel Bodony's love of science began with a love of airplanes. He worked for one of his dad's colleagues on the weekends who had an airplane. "I would mow his grass and he would let me fly," Bodony remembers fondly.

Production technology for more efficient jet engines

Aircrafts have to be more efficient – a crucial point when it comes to the design of jet engines. However, in the design of the components, the engineers also need to consider whether these can be economically produced. ...
