In Ancient Greek, one of the final two or three syllables of a word carries an accent. Each syllable may contain one or two vocalic morae, but only one can be accented; accented morae are pronounced at a higher pitch.
US military to launch fastest-ever plane. By the time you finish reading this sentence, the Falcon HTV-2, the fastest plane ever built, could have flown 18 miles. It would get from London to Sydney in less than an hour, while withstanding temperatures of almost 2,000C, hotter than the melting point of steel.
I have to agree with Sean Patrick: the fastest fighter jet is or was the YF-12. The question itself would left room for fantasy jets as well, but I will stick to a plane that was really built and that really flew. The YF-12 was not only the fastest, but also the biggest fighter jet ever built. Some sources also said that it would have been the best fighter jet in its time- flying with a speed of 3660km/h in an altitude of more than 27000 meters would have make it nearly impossible to shoot down- this was even about 5000 meters higher than a Mig-25 can fly.
