Bell X-1, 29 Aug 1947 - piloted by Chuck Yeager
super sonic
Supersonic aircraft are those that can exceed the sound barrier. I.e. Concorde was capable of this. Any craft that can exceed 1 to 5 times the speed of sound falls in this category.
The first American pilot to exceed the speed of sound in an airplane was Chuck Yeager.
Charles Yeager was the first person ever to pilot an aircraft beyond the speed of sound.
The first powered, manned aircraft was called the Wright Flyer. It was built by Wilbur and Orville Wright and first flew on December 17, 1903 at Kitty Hawk, North Carolina.The name of the first heavier-than-aircraft was the 1903 Wright Flyer. The plane was designed and built by Orville and Wilbur Wright. The engine was designed and built by Charles E. Taylor. The aircraft is on display in the Smithsonian Museum of Flight in Washington DC.

pilot an aircraft faster than the speed of sound
You can't really encounter a sonic boom, but sonic booms do occur when aircrafts exceed the speed of sound.
This is because the pressure needed to break the sound barrier is impossible to exceed but on the way back, the pressure is reduced and gravity pulls the aircraft down and the pressure for the sound barrier is reversed so it is a bit easier.
Yes, the word "demand" has a short "a" sound, pronounced as "duh-mand" with stress on the first syllable.
Chuck Yeager.
Chuck Yeager is credited with being the first pilot to break the sound barrier on October 14, 1947 in a Bell X-1.
