Supersonic plane
If the unidentified he refers to Chuck Yeager, then it was the Bell X-1.
NO they can not travel faster than sound in thunder and lightning
Because the molecules are less dense and they vibrate faster letting sound travel faster
Sound DOES travel faster in solids than in gases. The higher the density of the medium, the faster the sound travels.
You would hear the sound after the plane has passed.
no. sound is sound so how on earth can it be faster than itself? answer that!
Supersonic planes travel faster than sound. There are a lot of them. Most modern fighter jets can do it, and there have even been commercial planes that could (eg Concorde, Tu-144).
Sound travels faster in moist air
yes, the fastest plane in the world, the Lockheed SR-71 Blackbird, can reach speeds of up to three times the speed of sound.
yes, sound does travel faster in some gases, but it usally dipends on the temperature. it trave l faster in warm air.
