EAST RUTHERFORD, N.J. (CBSNewYork)Thanksgiving may still be more than three weeks away, but preparations for the annual Macy’s Thanksgiving Day Parade are already in full swing.

CBS2’s Marc Liverman got a preview at the Meadowlands on Saturday, where some of the biggest stars of this year’s parade went on a test flight at “Balloonfest.”

John Piper, vice president of production for Macy’s Parade Studio, says it’s fun to debut the brand-new balloons at the event, but there’s also a technical element to the day.

“Today is their final test flight, so we’re going to have the teams who will actually be piloting them and captaining them down the parade route here to take them for a run, a couple of laps around this parking lot so we can see exactly how they perform with the wind from each direction and the balance of the balloon with all the handlers,” said John Piper, vice president of production for Macy’s Parade Studio.

New balloons for the 93rd Macy’s Thanksgiving Day Parade include Smokey Bear, SpongeBob SquarePants and Gary, the Peanuts character Snoopy dressed as an astronaut and “Green Eggs and Ham” from the new Netflix show based on the Dr. Seuss book.

Piper says a typical balloon takes anywhere from five to nine months from “the time we start putting pencil to paper” until the Balloonfest test flight.
