> 15 km/s That's over mach 40 and would allow you to circumnavigate the globe in 45 minutes. There are flight vehicles that travel mach 20+, but 40 sounds insane. Mach also isn't the best numbers to use. The HTV-2 goes Mach 20+ but that's 5.7 km/s. Granted it is 2010 technology (first flight) but it would be insane to think we've doubled the speed and are testing these vehicles. It isn't like you can fly vehicles that fly that fast secretly. They make A LOT of noise. Measurement errors sounds like a better explanation. Especially when we have such strong evidence of other things (like tic-tac) being measurement errors. |
