The plane was a modified five-seat passenger plane, adapted for long-distance flight, with the passenger seats replaced by extra fuel tanks. Gains in flying time came at a cost: as one can see, Lindbergh had to dress heavily to stay warm in the cold, thin air.

Transcript
Of all forms of flight, hot air ballooning has the longest history. Human flight began with the Montgolfier brothers' first flights over Paris in 1783. They impressed the French King Louis XVI and America's Benjamin Franklin. The Montgolfiers made their balloon from paper and cotton, and heated the air by burning straw.
While today's hot air balloons are more sophisticated and durable, the principle behind them is the same as in the Montgolfier brothers' time:
Heat a large volume of air to make it less dense, and therefore able to rise.
If a balloon captures enough hot air, the balloon will be buoyant enough in the atmosphere to lift humans off the ground.
Long ago, people saw hot air rise in smoke from candles. They witnessed clouds rise over hot fields. But in the Montgolfiers' time, the science of gasses gained fresh understanding. This knowledge encouraged the Montgolfier brothers' experiments with capturing hot air, to harness it for lift.
Once a novelty, hot air ballooning is now a widespread activity. Festivals celebrate ballooning in the Americas, Australia and Europe. In Africa, balloon tours take guests aloft to view herds of wild animals on the savannah. Ballooning today is a popular sport.
