Yes, jets are airplanes but they are called supersonic airplanes.
The Concorde was the first and only supersonic passenger airliner. Many other airplanes -- mainly military -- before and after it far exceeded its speed.
The kind of plane that have delta are the airplanes that fly very fast, usually over or near the supersonic speed (faster than the speed of sound). The type of airplanes that have the most delta wings are fighters, and some of the bombers such as the XB-70.

Speed has nothing to do with where you are. You can travel at supersonic speed pretty much anywhere if you have the right vehicle.
Supersonic means "Faster than the speed of sound" so they are not the sme thing.

The threshold for supersonic speed is 761 mph in a temperature like 70 degrees. Supersonic speed is any speed greater than the speed of sound (mach 1) and a speed five times the speed of sound (mach 5?) is referred to as hypersonic speed.
A supersonic bullet is a bullet that is faster than the speed of sound.
No such thing as supersonic sound. Things can move with supersonic speed (fighter jets, ends of whips) making a shock wave, but the sound arrives at your ears at the speed of sound.
Supersonic air craft.
When a jet flies at supersonic speed, it travels faster than the speed of sound. This can lead to the formation of shock waves that create a sonic boom. The aircraft may experience increased drag, higher temperatures, and changes in aerodynamic forces.
