Joseph and Jacques Montgolfier developed their first hot-air balloon in 1783. Joseph and Jacques were 2 of the 16 children of Pierre Montgolfier and his wife. The two brothers worked in the family run business, a paper factory at Annonay, a small town near Lyon in France. Their experiments were inspired by the rising of a shirt that was drying above a fire. They threw scraps of paper in the fireplace, which shortly afterwards could be seen leaving the chimney. From this they mistakenly concluded that smoke, and not hot air, had the power to lift. The density of hot air is less than that of cold air and just as air rises in water (water has a higher density than air), hot air rises in cold air. Despite their mistaken belief, the brothers' experiments led to the invention of the hot-air balloon.

On April 4, 1783, the brothers Montgolfier gave the first public demonstration of the hot-air balloon at Annonay. This unmanned balloon flew a distance of nearly 2 kilometres and reached a height of almost 2 metres. The balloon was made of fabric and was lined with white paper, coated with a layer of alum, which served as a fire resistant layer. The whole balloon was kept together by about 2,000 knots.

History of the Hot Air Balloon

September 19, 1783 ~ A sheep, a duck, and a rooster become the first passengers in a hot air balloon launched by the Montgolfier brothers, Joseph and Ettienne.

November 21,1783 ~ The first recorded manned flight in a hot air balloon took place in Paris. Built from paper and silk by the Montgolfier brothers, this balloon was piloted on a 22 minute flight by two noblemen from the court of Louis XVI and Marie Antoinette. From the center of Paris they ascended 500 feet above the roof tops before eventually landing miles away in the vineyards. Local farmers were very suspicious of this fiery dragon descending from the sky. The pilots offered champagne to placate them and to celebrate the first human flight, a tradition carried on to this day.

January 19, 1784 ~ In Lyon, France, the only recorded flight by Joseph Montgolfier was made in one of the largest balloons ever made.

September 15, 1784 ~ An Italian, Vincenzo Lunardi, made the first balloon flight outside of France. The 500 cubic metre balloon flew from Moorfields in England and landed near Ware.

November 30, 1784 ~ Launching their balloon from Rhedarium Garden, London, another Frenchman, Jean-Pierre Blanchard, and an American, John Jeffries, make their first flight.

January 7, 1785 ~ the same team of Jean-Pierre Blanchard and John Jeffries became the first to fly across the English Channel.

January 9, 1793 ~ the first flight of a balloon in North America occured in Philadelphia and was piloted by Jean-Pierre Blanchard.

October 10, 1960 ~ the official birth date of the modern hot-air balloon. The first man-carrying free flight took place at Bruning, Nebraska, in the Raven prototype ‘modern’ hot-air balloon. The 30,000 cu ft envelope was constructed of a polyurethane coated nylon and the burner was propane powered.

By 1963, the growing sport was able to sustain the first U.S. national championships.

The balloons used for passenger flights today were developed in the United States during the 1960s and have two main technological advances: using rip-stop nylon, a very safe and reliable material for the envelope and running a LPG gas burner to heat the air in the envelope. Ballooning began as a sport with a few enthusiasts in the USA and England and spread to Australia in the 1970s. Today there are over 5,000 balloon pilots in the U.S. alone.

Timeline of Ballooning

On October 15, 1783, a certain Francis Pilatre De Rozier, a member of the Academy of Sciences, took off with a Montgolfiere, a type of balloon named after the inventors. He reached a height of 28 meters and was connected to the earth by means of a cable. This height was improved upon in the following days from 60 to 80 metres and then twice, 96 metres. The second time De Rozier was accompanied by the marquis d'Arlandes. On November 21, 1783, at 13.45 hours, the first untethered / free flight in the history of mankind was at last made.

At a height of approximately 90 metres, both gentlemen took off their hat for the crowd, which had gathered beneath them and was holding its breath in suspense as it watched. The balloon then rose to a height of 900 metres and eventually landed eight km further after a 25 minute flight.

Of course in time, various changes were to be made to the balloon. A burner was attached in which straw and wool could be burned. A circular walkway was added at the bottom part of the balloon, in which the first 'aeronauts' could stand.

For even later types, a strap was constructed which looked quite like a small boat. In the beginning these small 'boats' were equipped with a kind of oar, because they believed they would be able to row in the air. They believed the balloon could be steered in a certain direction.

First manned flight

On September 19, 1783, the Montgolfier brothers let the first living beings be lifted by a hot-air balloon, namely: a sheep, a hen and a duck. They made a flight which lasted 8 minutes, from Versailles, with Lodewijk XVI as observer and reached a maximum height of 500 metres and landed, unharmed, in the forests of Vaucresson, 3.5 kilometres from their starting point.

Flying Animals

Both the Union and Confederate armies used balloons for reconnaissance during the American Civil War, marking the first time that balloons were used in the United States for reconnaissance. The professional aeronaut John Wise was the first to receive orders to build a balloon for the Union army. However, the balloon never was used because it escaped its tethers and was shot down to prevent it from falling into Confederate hands.

Thaddeus Lowe and John LaMountain both carried out reconnaissance activities for the Union army during the war. Lowe had foreseen the usefulness of balloon observations when he had accidentally landed in South Carolina on a flight from Cincinnati, Ohio, to the Atlantic Ocean in April 1861. One of his financial supporters, Murat Halstead, editor of the Cincinnati Daily Commercial, wrote to U.S. Treasury Secretary Salmon P. Chase and suggested that the United States establish a balloon corps under Lowe's command. This corps would provide aerial reconnaissance for the Union armies.

Secretary Chase arranged a meeting between Lowe and President Abraham Lincoln for June 11, 1861. On July 17, 1861, Lowe demonstrated his ideas for balloon reconnaissance and also for sending telegrams from the balloon to the commanders below. He used the Enterprise, attached to tethers and floating 500 feet (152 meters) above Washington, D.C. President Lincoln was duly impressed. Later that summer, President Lincoln established the Balloon Corps, a civilian organization under the authority of the Union's Bureau of Topographical Engineers, and granted Lowe permission to requisition equipment and personnel.

Lowe received funds to build a balloon on August 2, 1861. The first U.S. balloon designed for military use, the Union, was ready for action on August 28. Because he was forced to inflate the balloon with gas from municipal lines in Washington, D.C (he had not received his funds yet for a portable gas generator), the balloon could not be moved far, which limited operations to the Washington, DC, area.

On September 24, 1861, Lowe ascended to more than 1,000 feet (305 meters) near Arlington, Virginia, across the Potomac River from Washington, DC, and began telegraphing intelligence on the Confederate troops located at Falls Church, Virginia, more than three miles (4.8 kilometers) away. Union guns were aimed and fired accurately at the Confederate troops without actually being able to see them—a first in the history of warfare.

This triumph led the Secretary of War Simon Cameron to direct Lowe to build four additional balloons. Two more followed shortly. The fleet now consisted of the Intrepid, Constitution, United States, Washington, Eagle, Excelsior, and the original Union. The balloons ranged in size from 32,000 cubic feet (906 cubic meters) down to 15,000 cubic feet (425 cubic meters). Each had enough cable to climb 5,000 feet (1524 meters).

At the same time, fellow aeronaut John LaMountain was also attempting to provide balloon services for the Union. He wrote to Secretary Cameron in 1861, but, because he had no influential backers, LaMountain did not receive a reply. However, the commander of the Union Forces at Fort Monroe, Major General Benjamin F. Butler, contacted him and asked for a demonstration. Using the Atlantic, which he had used to attempt to reach the Atlantic Ocean earlier, he made two successful ascents at Fort Monroe in July 1861. The New York Times reported that LaMountain could view the Confederate encampments beyond Newmarket Bridge, Virginia, and also at the James River north of Newport News. LaMountain had actually made the first aerial reconnaissance of the Civil War and also was the first to gather intelligence by free balloon flight rather than from a tethered balloon.

LaMountain, however, did not have the Union Army behind him, and he had difficulty obtaining equipment. He managed to obtain another balloon, the Saratoga. That balloon, however, was lost on November 16, 1861. He tried to get some of Lowe's equipment, but Lowe refused to cooperate. Each man found supporters, and the rivalry between the two grew. Finally, after accusations and hostilities on both sides, on February 19, 1862, General McClellan dismissed LaMountain from any further service to the military.

Lowe continued providing tactical reports to the Union troops. He provided information during the siege of Yorktown, Virginia, and in late April 1863, at Fredericksburg, he transmitted hourly reports on Confederate movements. During the battle of Fair Oaks, Virginia, Lowe continually transmitted information on enemy troop positions. Observations made during this battle proved to be crucial to the Union victory.

The presence of the balloons forced the Confederates to conceal their forces. To avoid detection, they blacked out their camps after dark and also created dummy encampments and gun emplacements, all of which took valuable time and personnel.

However, the balloon corps did not last until the end of the war. General George McClellan was relieved of his command in 1863, and Captain Cyrus Comstock, who was assigned to oversee the balloon corps, cut its funding and thus its effectiveness. Lowe was also accused of financial impropriety, and his pay was reduced. Lowe resigned from the balloon corps on May 8, 1863. By August 1863, the corps had disbanded.

As well as aerial reconnaissance and telegraphy, Lowe and LaMountain also introduced the use of aircraft carriers. Lowe directed the construction in 1861 of the first aircraft carrier, George Washington Parke Custis, a rebuilt coal barge with a flight deck superstructure. On one occasion, she towed one of Lowe's balloons for 13 miles (21 kilometers) at an altitude of 1,000 feet (305 meters) while Lowe made continuous observations. On August 3, 1861, LaMountain used the deck of the small vessel Fanny to launch an observation balloon 2,000 feet (610 meters) over the James River. He used the Union tugboat Adriatic for the same purpose. Word of the Americans' achievements even reached Europe, where the Prussian army sent Count Ferdinand von Zeppelin to learn what he could from this kind of warfare.

Some authorities claim that, although balloon observations contributed to battle victories, the Union Army's commanding generals did not use the balloon observations advantageously. Vague reports on Robert E. Lee's movements issued from the hydrogen balloon Intrepid during the 1862 Peninsula Campaign apparently served only to panic General McClellan. The general withdrew his vastly superior forces and positioned them seven miles (11 kilometers) from Richmond, Virginia, rather than attacking the sparsely defended Confederate capital and ending the war three years and tens of thousands of lives sooner. After McClellan was relieved of his command, Ulysses S. Grant took over and reorganized the Army of the Potomac. Preferring to rely more on attrition than on intelligence, he disbanded the Balloon Corps.

The Confederate Army also formed a smaller version of the balloon corps. In the spring of 1862, Captain John Randolph Bryan offered to oversee the building and deployment of an observation balloon. This balloon consisted of a cotton envelope coated with varnish. Unlike the hydrogen-filled Union balloons, it was a Montgolfiére—filled with hot air—because the Confederacy did not have the equipment for generating hydrogen in the field.

Bryan launched the balloon on April 13, 1862, over Yorktown, Virginia. Even though the balloon was rotating on its single tether while aloft, Bryan managed to sketch a map of Union positions. On his next flight, Bryan ended up in free flight after the tether was cut to free an entangled ground crew member. He was fired upon by Confederate troops below who thought he was the enemy, but managed to escape and land safely.

The second Confederate balloon was constructed of multi-colored silk, which gave rise to the legend that this Confederate balloon was made from silk dresses donated by the ladies of the Confederacy. Although the "Silk Dress Balloon" was constructed from dress silk, no actual dresses were sacrificed. This balloon was gas-filled in Richmond, Virginia, and carried to the field by tethering it to a locomotive. In 1862, when the battle area moved too far from the railroad, it was attached to a tugboat and carried down the James River where the tug, unfortunately, ran aground and was captured.

Another "Silk Dress Balloon" was constructed and went into service at Richmond in the fall of 1862. It provided aerial observations from its post until the summer of 1863 when it escaped in a high wind and was captured by Union troops.
