As explained by NASA, airplanes are able to fly because of lift. … A main reason airplanes can’t fly in space is because there is no air. According to NASA, large commercial airplanes typically can’t fly higher than 7.5 miles. At this altitude, the air isn’t dense enough to support a large airplane.
Is there a plane that can fly into space?
A spaceplane is a vehicle that can fly/glide like an aircraft in Earth’s atmosphere and maneuver like a spacecraft in outer space. … Three types of spaceplane have successfully launched to orbit, reentered Earth’s atmosphere, and landed: the Space Shuttle, Buran, and the X-37.
Why can’t commercial planes fly into space?
Planes can and have flown into space for over 50 years – though not the kind you see at the airport. That’s because conventional planes need air for both propulsion and lift, and space is essentially a vacuum.
Could a fighter jet fly into space?
Even the most modern of fighter jets cannot fly into space. The F-35 Lightning II, considered to be the world’s most advanced craft, has a service ceiling of around 15 kilometres (nine miles). … Part of the reason fighter jets can’t fly this high is their power source. Jet engines rely on air intake to function properly.
What happens if a commercial plane flies too high?
When the plane gets too high, there is insufficient oxygen to fuel the engines. “The air is less dense at altitude, so the engine can suck in less and less air per second as it goes higher and at some point the engine can no longer develop sufficient power to climb.” …
How many feet up is space?
In the US, “space” begins at 80.4km (50 miles), or 264,000 feet. General international consensus sets a similar limit for the start of space as 100km (62 miles), or 380,000 feet. “Low Earth Orbit” (LEO), where many satellites live, goes from 160km (100 miles, 525,000 feet) to 2,000km (1,240 miles, 6.5 million feet).
Can an airplane fly without fuel?
The world’s first zero-fuel plane is finally close to flying around the world. For the first time in history, a solar-powered plane is flying around the world — all without a drip of fossil fuel. … The plane has the wingspan of a Boeing 747, weighs as much as an SUV, and travels just 43 mph.
What will happen if planes fly almost to space?
If an airplane flies in space, it won’t be able to suck in fresh air with which to supply its engines, resulting in loss of propulsion. The bottom line is that airplanes can’t fly in space because there is no air in space. Airplanes rely on air to produce both lift and propulsion.
How high can a commercial jet fly?
Most commercial aircraft are approved to fly at a maximum of around 42,000 feet. This maximum is also known as a ‘service ceiling.
Can birds fly in space?
Birds cannot fly in the vacuum of space because there is no air, but some birds have been brought to live on space stations before. American astronauts brought 32 chicken embryos to space on the Discovery STS-29 flight. … Adult birds have not been taken to space and would not be able to fly outside of a space station.
Why do planes not fly directly over the Pacific Ocean?
The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes. … Whether a commercial airline is flying from the United States to Asia or elsewhere, it will have the fastest and most fuel-efficient flight by performing a curved rout.
Can a civilian fly a fighter jet?
Yes, civilians can fly military aircraft including jets.
Why do jets fly at 35000 feet?
The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.
What limits how high a plane can fly?
While there is no official maximum altitude for flying from aviation authorities, aircraft carriers have their own maximum heights that they are capable of flying. Private planes and commercial jets can go up to 42,000 feet, while smaller aircraft often stay around 10,000 feet.
Can an airplane stay still in the air?
Can an Airplane stand still in mid-air? Technically, it is possible for an airplane to hover for a few moments, but only in the rarest of circumstances. If weight and lift cancel each other out at the same exact time that thrust and drag cancel each other out, the plane would hover until one of these variables changed.
What happens if a helicopter flies too high?
What Happens If a Helicopter Flies Too High? As the helicopter ascends, the air begins to thin. With thinner air, the main rotor becomes less efficient. The higher the helicopter flies, the slower it ascends due to the reduced power generated by the rotor.
