altitude

A better understanding of the processes involved in retaining water in the snow and the integration of dynamic parameters, such as changes in the altitude of the ice sheet, are essential to reduce uncertainties.

The cabin altitude checklist includes "immediate use of oxygen masks".

The plane, a Mooney M20 with two passengers, climbed to about 2,100 feet and 110 miles per hour before rapidly losing altitude about 1:45 p.m., according to its flight track log.

“There does appear to be an environmental factor which played a role in both the establishment of the cities in high altitude — in this case areas rich in ore and other resources,” Frachetti said.

“All the parameters — speed, altitude — match those of an intercontinental ballistic missile,” he said.
