In what may be the strangest traffic stop of the day, sheriff’s deputies forced two hot air balloon pilots to land their bulbous crafts when authorities began to receive numerous 911 calls about the brightly colored orbs coming dangerously close to rooftops and striking the tops of trees in a Yucaipa neighborhood Tuesday morning.

“Both pilots were found to be hot air balloon enthusiasts, and were flying their privately owned balloons for personal use,” according to a San Bernardino County sheriff’s Yucaipa station press release.

The calls started to come into sheriff’s dispatch shortly before 8 a.m. reporting the two balloons were flying very low and may have crashed into homes in the 34700 block of Maplewood Lane in the Chapman Heights neighborhood, the statement said.

Deputies went to the neighborhood and spotted the balloons — one green, the other blue — flying above the golf course, “at times coming within 5 feet of rooftops and hitting trees,” officials said.

Deputies were able to get the pilots’ attention and asked them to land immediately. One balloon landed safely land in a high school baseball field. Though the release didn’t name the school, the closest high school to the golf course is Yucaipa High School. The second balloon was able to land in an orange grove at a private home in Mentone, officials said.

Deputies identified and spoke to the pilots and authorities will be forwarding a report to the Federal Aviation Administration for further review of any possible FAA violations, sheriff’s officials said.

As of late Tuesday morning, officials were unable to find any instances of damage either to the hot air balloons or damage caused by them. No one was hurt during the incident.

Authorities ask anyone with additional information to call Detective Donald Patton at the Yucaipa station.
