Aeronaut Adventures
In many ways, ballooning is not very different from any other type of flying. The challenges are similar, as are the some of the hazards. Some aeronaut reporters to ASRS share a few of their “hot air” stories with us.
Capricious Winds–and Fortune
More so than in powered flight, hot air ballooning is at the mercy of the “wind gods” who often offer up capricious winds, or sometimes no winds at all. A controller’s report provides evidence:
Notable Landings
An unwritten rule for hot air balloonists is never to pass up a good landing site for a poor one. As such, some aeronauts recall their notable landing sites.
■ Our flight finally started 50 minutes prior to sunset. I
became concerned with lack of landing sites and closeness to sunset. Finally, with only 15 minutes before sunset, I landed in the center of a highway cloverleaf. Luckily for this reporter, the local police were more curious than punitive...
■ Two hot air balloons departed near the exterior bound
aries of the ATA [Class D Airspace]. Because of winds, they entered the ATA and became a factor for several aircraft. These balloonists probably wanted to fly out of the ATA as much as the controller wanted them to, but most likely couldn’t tell ATC this. Even though a few balloonists carry handheld radios, most are incommunicado.
■ I landed in a suitable area at a school. The Vice-Principal
approached and advised me that summer school was in session and the property was off limits. Some state Departments of Aeronautics strictly control aircraft landings on school property (usually only K-12), regardless of whether or not the school is in session.
A Kiss, Not a Miss
■ Contact with another hot air balloon...fabric-to-fabric
[and] no damage to either aircraft. I should have looked closer behind and below. This no-damage mid-air collision is known as a “kiss,” and might have been avoided had the reporter given way to the lower balloon. This incident serves as a gentle reminder to all pilots to review right-of-way rules–and to see and avoid.
■ I was flying over the lake, winds went calm...and we de
cided to land the balloon in [a friend’s] boat. I elevated the basket, he slipped under with the boat, and I sat it down in the boat and collapsed the envelope. According to our reporter, the need for an ASRS report arose when “one of the boats reported to the local FAA that the balloon had ‘crashed’ in the lake...” This was probably not the first time a balloon has needed a little help getting to shore. Another aeronaut needed help getting out of the “pen”:
Low-Level Hazards
■ Launched in good VMC conditions. While I was
performing high altitude maneuvers, ground fog started to form. I maneuvered with reference to objects projecting above the fog, and began a slow descent. I established ground contact at approximately 100-200 feet AGL. Primary cause of the incident was not being more aggressive about landing at the first sign of fog formation. Not every pilot has such a benign encounter with unforecast IMC. This pilot was fortunate to be able to descend without interference from powerlines, trees, or some other obstacle hidden in the fog–unlike our next aeronaut: Another pilot and I were floating up a river [in a balloon] when we came upon some well hidden powerlines. We brushed the lines, but no damage occurred. Powerlines, especially those embedded in trees, continue to be a hazard to all types of low-flying aircraft. Pilots are re sponsible for determining when low-level flight is safe and appropriate, and when it is simply not worth the risk.
■ The wind was picking up on the surface. I decided to land
in the hayfield directly in front of us. We were met by two Corrections Department employees, informing us that we had landed on prison property!
A Note To Our Readers
The April issue of Callback experienced unexpected productions delays that will result in readers receiving it much later than usual. The May issue should be produced on time. We regret this departure from our usual schedule.
