    Kincheloe flew 2000 miles per hour (3,200 km/h) at 126,000 feet (38,500 m), or 24 miles up. At this altitude and speed, aerodynamic lift still carries 98 percent of the weight of the plane, and only two percent is carried by inertia, or Kepler force , as space scientists call it.

    Mauna Loa (4,169 m or 13,678 ft) is the largest mountain on Earth in terms of base area (about 5,200 km 2 or 2,000 sq mi) and volume (about 42,000 km 3 or 10,000 cu mi), although, due to the intergrade of lava from Kilauea, Hualalai and Mauna Kea, the volume can only be estimated based on surface area and height of the edifice.

    On land, the league is most commonly defined as three miles (4.83 km), although the length of a mile could vary from place to place as well as depending on the era. At sea, a league is three nmi (3.452 mi; 5.556 km). English usage also included many of the other leagues mentioned below (for example, in discussing the Treaty of Tordesillas).

    At heights over 100 km, an atmosphere may no longer be well mixed. Then each chemical species has its own scale height. In summary, the mass of Earth's atmosphere is distributed approximately as follows: [43] 50% is below 5.6 km (18,000 ft), 90% is below 16 km (52,000 ft), 99.99997% is below 100 km (62 mi; 330,000 ft), the Kármán line.
