Who died on MH370?
All 144 passengers and six crew members, including Lubitz, were killed.
Why do planes depressurize?
When a cabin depressurizes, the percentage of oxygen in the air stays about the same, but the molecules get further and further apart, Padfield explained. Then the air expands through an expansion turbine that cools air in the same way you can cool air by blowing it out of puckered lips.
Can a bullet depressurize a plane?
If the bullet simply punctures the skin of an airplane, then it’s no big deal. The cabin of the airplane is pressurized, and the hole creates a small leak, but the pressurization system will compensate for it. When the window blows, the plane will depressurize over the course of several seconds.
How high can you fly without oxygen?
When the altitude of an airplane is less than 12,500 feet, there is no supplemental oxygen required for anyone in a private plane. From 12,500 feet to 14,000 feet, supplemental oxygen must be used by the required flight crew for any portion of the flight that is more than 30 minutes.
How high can you fly unpressurized?
10,000 feet
Can you breathe at 20000 feet?
It is the lack of oxygen rather than the reduced air pressure that actually limits the height at which we can breathe. An elevation of about 20,000 feet above sea level is the maximum height at which sufficient oxygen exists in the air to sustain us.
How cold is it at 24000 feet?
Standard atmospheric pressure at sealevel = 29.92 inches of Hg. Temperature — As air is warmed, it expands and thus has a lower density. Hot air rises, which is what keeps hot-air balloons up, and cold air sinks. Standard atmospheric temperature at sealevel = 59.0°F.
How cold is it at 35000 feet in the air?
about -54C
Why do planes not freeze in the air?
The absence of water in colder temperatures means there is nothing to form ice from. These droplets do not have a freezing nuclei and thus will stay liquid even at temperatures below zero. However, when an airplane comes in contact with it, the airplane acts as the freezing nuclei, freezing the droplets immediately.
What temp do planes stop flying?
“Jet fuel begins to gel in extreme conditions and does eventually freeze, typically at minus 40 or so, although additives can be included that reduce that further,” says Haines. “Aircraft at cruising altitude will often experience temperatures of minus 50 to minus 70 F for hours on end.”
