The Engineering Behind the Macy’s Thanksgiving Day Parade Balloons

November 24 is Thanksgiving, and while we will spend time around the dinner table next Thursday evening, many people will kick off the day by watching the Macy’s Thanksgiving Day Parade.

If you’ve ever wondered about all the science and engineering behind the parade, read on.

When engineering a new balloon design, creators first sketch out a diagram, which is examined and adjusted by engineering experts, to ensure that the design will safely float. Then dimensions are determined and a real-size clay model of the design is created, to calculate how much fabric and helium is needed.

The float then goes through months of testing, conducted by dozens of handlers. The tests are to ensure proper inflation and deflation, easy handling, etc. Then the finishing touches are added to the balloon.

Fun Facts:

  •  It takes 90 minutes to inflate a parade balloon and 15 minutes to deflate one.
  • The average balloon requires 12,000 cubic feet of helium. That’s enough to fill about 2,500 bathtubs.
  • Balloon pilots must attend training and must be able to walk the parade route backwards. Balloon handlers support the pilot and help maintain control of the balloons. They must weigh at least 120 pounds and be in good health.

Engineers Who Have Contributed to the Development of Aviation

November is National Aviation History Month. While we may be focused on the upcoming holidays, many people are fascinated with aviation and the pioneers who’ve contributed to and helped shape aviation in today’s society.

If you’ve ever wondered about the first pioneer engineers behind aviation, read on.

In the early days, prior to designing and executing the first flight, engineers conducted many experiments and extensive research to determine the four component forces that enabled design and/or flying of an aircraft, which are thrust, lift, drag, and weight. This was the birth of aeronautical technology.

According to the U.S. Bureau of Labor Statistics (BLS), “aeronautical engineers work with aircraft. They are involved primarily in designing aircraft and propulsion systems and in studying the aerodynamic performance of aircraft and construction materials. They work with the theory, technology, and practice of flight within the Earth’s atmosphere.”

The following aeronautical engineers are some of the pioneers who changed aviation history:

  • Jules Henri Giffard studied the notes of an inventor named Pierre Jullien who display a cigar-shaped model airship at the Paris Hippodrome. Jullien’s design helped Giffard became the first person to build a full-size airship;
  • Brothers Orville and Wilbur Wright are known for executing the first flight, which lasted 12 seconds;
  • Charles Lindbergh is known for performing the first solo transatlantic flight; and
  • Amelia Earhart is a known aviation pioneer and was the first solo female aviator to complete a transatlantic flight.
