Joseph is switching to ‘vacation mode’ and Dr. Carter shares stories about his fun adventures in Florida. In an interesting story of science news this week, researchers think they can accurately say that the Milky Way galaxy wobbles! In listener questions: what is acid rain? For the main topic, Rob tells us all about the jet engine! In the after show, Beequinox is back! Wow!

This week we explore the science of flight. Dr Graham Taylor from Oxford University talks about the aerodynamics of insect flight and how video camera back-packs allow him to see how eagles fly, and Jenny Goodman describes how future aircraft might be flying at six times the speed of sound while withstanding temperatures hot enough to melt stainless steel in 5 seconds! In Kitchen Science, Ben Valsler sticks with the flight theme and finds out how a hot air balloon works. Like this podcast? Please help us by supporting the Naked Scientists
