F-15 Streak Eagle Record Flights Part 1

The Streak Eagle attempts to break numerous world air records. Even if you don't like airplanes, just play it for the music. You'll notice that the Streak Eagle isn't painted, that's to reduce overall weight and make it go faster. You'll also notice that before take off, it is chained to the runway and then released. This is to build up as much potential energy as possible before the plane takes off. Finally, you'll notice the aircraft takes a roundabout way of getting to altitude. Rather than go straight up, the Streak Eagle follows its "energy curve" which is the path where the aerodyanmics allows the aircraft to maximize its power. It's all very nerdy and engineering, but if you see the chart with the energy curve, it will make sense. This is also the reason the F-22 cannot beat the F-15s time to climb record, even though the Raptor has more powerful engines. If you watch the entire video (and you should), the narrator states that the F-15 has a faster time to climb than the Saturn V rocket, so a more powerful engine doesn't necessarily mean a faster time to climb. It has a lot to do with geometries and whatnot. Take an aerodynamics class to learn more! Don't forget to check out part 2 of this vid!
