8,000 feet into the atmosphere
The 700 mb level of the atmosphere is 10,000 feet in the air. This level is the second level used for measuring the atmosphere in the troposphere, so 1/5 of the atmosphere is located below it.
No. The Concorde, as with any airplane, is dependent on the atmosphere to keep it above the ground, through its wings. The Concorde has a maximum "ceiling" of 60,000 feet, or about 12 miles above sea level (and about twice the elevation of Mt. Everest). If you could somehow stand on something at that height and be exposed to the atmosphere, it would be far too cold and the air too thin to survive, with only about 10 per cent of the air pressure that there is at sea level, but it is still significant. The Concorde is not capable of "flying" outside an atmosphere, as its jet engines require air to operate.

the atmosphere high above ground level
The stratosphere isn't on earth's surface, the troposphere is. The stratosphere is the next level of the atmosphere from the troposphere. the atmosphere is about 600 miles or kilometers above earth's surface.
Most people live in the Troposphere which is from sea level to 10 miles above sea level. Although some people live in the Stratosphere which is 10 miles above sea level to 35 miles above sea level. The Stratosphere is also where the weather comes from.
in the very very top
The pressure at any level in the atmosphere may be measured in terms of the total mass of the air above any point.
The atmosphere is densest at sea level, so as the density of air goes down, so does the atmospheric pressure. The atmosphere gets less and less dense as you rise higher above the sea level.
35K Feet = 10.668 KM Atmosphere = 560 KM Airplane at 35,000 feet would be above approximately 1.9% of the earth's atmosphere.
The cool atmosphere condenses the rising water vapor and causes it to fall back to Earth
The lowest level, which includes all human habitation and the weather, is the troposphere, and above it is the stratosphere.
This is the troposphere, the lowest level of Earth's atmosphere
