A balloon can fly, with proper weather conditions, up to 12,500 feet above sea level before oxygen is required.

A sheep, a duck and a rooster were the first passengers on a hot air balloon, brave pioneers of the modern era of flying. The modern era of flight was inaugurated in 1783, when a sheep, a duck and a rooster boarded a prototype balloon and flew for some eight minutes.

On November 26, 2005, Vijaypat Singhania set the world altitude record for highest hot-air-balloon flight, reaching 21,290 m (69,850 ft). He launched from downtown Mumbai, India, and landed 240 km (150 mi) south in Panchale.

Hot Air Balloons: The Dangers Although hot air balloon accidents are uncommon, they do happen, and they can result in devastating and sometimes fatal injuries. Even hard landings can lead to whiplash, broken bones in the upper and lower extremities, and traumatic brain injuries (TBI).

Because density is altered by altitude, the helium balloon can reach a height of 9,000 meters, or 29,537 feet. Anything higher than this altitude will cause the helium within the balloon to expand and the balloon to pop.

Because they are soft and malleable, latex balloons easily conform to an animal’s stomach cavity or digestive tract and can cause obstruction, starvation and death. As a result, latex balloons are the deadliest form of marine debris for seabirds. They are 32 times more likely to kill than hard plastics when ingested.

High-altitude balloons are crewed or uncrewed balloons, usually filled with helium or hydrogen, that are released into the stratosphere, generally attaining between 18 and 37 km (11 and 23 mi; 59,000 and 121,000 ft) above sea level.

So even if a helium balloon can wreck an engine, the likelihood that’s going to cause a plane crash is extremely slim. If you are referring to a “party balloon” the answer is yes & no. Yes it can be sucked into an engine & no it won’t stop the engine & thus cause the aircraft to crash — it won’t even hiccup.

Large clusters of free-flying helium-filled balloons may distract pilots during critical stages of flight (such as take-off or landing) and/or be ingested by aircraft engines. This may in turn endanger lives and cause harm to the property – in the air and on the ground.

A helium-filled balloon can float very high up into the atmosphere, however, it cannot float up into outer space. The air in Earth’s atmosphere gets thinner the higher up you go. This happens at about a height of 20 miles (32 kilometers) above Earth’s surface. So, this is as far as a helium balloon can rise.

No. The reason is simple- they’re too lightweight. The FAA (and other aviation safety organizations in other nations) have set standards up, after considerable testing, that prevent unpiloted balloons from being dangerous in the skies.

The balloons are used to measure temperature, pressure and humidity. They are filled with hydrogen gas and they soar up to 100-thousand feet in the sky. So weather balloons are definitely real and they while they are somewhat simple they are still considered the best way to measure atmospheric conditions.

around 2 hours

In two hours, a weather balloon can rise above the clouds, higher than the paths of jet planes, passing through the ozone layer in the stratosphere.

Weather balloons are launched around the world for observations used to diagnose current conditions as well as by human forecasters and computer models for weather forecasting. About 800 locations around the globe do routine releases, twice daily, usually at 0000 UTC and 1200 UTC.

Do weather balloons light up at night? Weather balloons have no on-board illumination, but in twilight they can be in sunlight while it is dark down below and the sky is darkening. In these circumstances they will stand out as a bright object that may be slowly moving with respect to the stellar background.

Helium can lift approximately 1 gram per liter. Thus, you need approximately 80000 liters of helium to lift said person, or in other words, it would require 80000 / 14 5714 balloons.

To lift a 200 pound person, you would need a spherical bag of hydrogen about 18 feet across.

(Most houses weigh between 80,000 and 160,000 pounds.) Given that 1 cubic foot of helium can lift 0.067 pounds, it would take 1,492,537 cubic feet of helium to lift the house—or about as much as would be contained in 105,854 balloons, each 3 feet in diameter.

12 lbs

So a helium balloon has two opposing forces acting on it: gravity pulling it down, and buoyancy pushing it up. Buoyancy wins, so you can’t really weigh a balloon, even though it does have weight.

A cubic foot sounds about right for a standard helium balloon. So you’d need 16 balloons for every pound of dog, plus 16 balloons for every pound of harness and straps (and doggles, and parachute — safety first). Oh, add a few more to make sure you’ve got positive buoyancy.

Well helium can lift roughly 1 gram per liter of helium gas. The average inflated balloon has a volume of about 113 liters, so can lift roughly 110 grams. To lift a 1000 kg car (1,000,000 grams) we’d need 1,balloons. About 9100 balloons!
