An F-15 can typically stay aloft for about 2 to 4 hours without refueling, depending on its mission profile, payload, and speed. The exact duration varies based on factors like fuel load, operational conditions, and whether it is engaged in combat or flying at cruising speeds. In practice, air-to-air refueling significantly extends its flight time, allowing for prolonged missions.
Weather balloons typically stay aloft in the atmosphere for about 12 to 24 hours before they burst and fall back to the ground.
The question is not well-formed. Similar questions may include: How many minutes does a helium balloon stay aloft? How long does a hot air balloon stay aloft? How long does a particular rocket motor burn?
Eagles are exceptional gliders. So, as long as a bald eagle has lift beneath his wings, he can stay aloft.
Albatrosses are thought to stay aloft for 30 days at a time, but no-one sees them land on the water to rest. They do need a lot of wind to get them aloft again, so they probably try to keep that to a minimum.
The act of moving smoothly along a surface while remaining in contact with it
The rotors provide lift to keep them up.
You can stay in Panama for up to 180 days without a visa.
A plane with no engine is a glider. They use the air currents to stay aloft.
I don't know and I don't care either.
As long as you want. I think the question you are trying to ask is "How long can you stay in Chernobyl without dying?".
The duration a jet can fly without refueling varies widely based on the aircraft type and design. For example, commercial airliners like the Boeing 777 can fly for approximately 15 hours, while long-range military jets like the Boeing KC-135 can stay airborne for around 12 hours. Some specialized aircraft, like the Global Hawk drone, can operate for over 30 hours. Ultimately, the flight duration is influenced by factors such as payload, altitude, and weather conditions.
As a tourist, you can stay in Japan without a visa for up to 90 days.
