What Happens in Balloon Incidents
In truth, probably all of the balloon
incidents could be considered weather
related, as low-level flights to find
suitable landing sites, landing in residential
areas, and hard landings are
usually caused by winds that are not
favorable to the balloonist. Even some
of the ground incidents undoubtedly
involved unreported weather factors.
Airspace Problems
Eleven of the incidents reported involved
airspace violations by aeronauts
who found themselves inside
the edge of Class “B,” “C,” or “D” airspace
without proper radio contact
due to a wind shift, faulty or no radio,
or faulty navigation. Two aeronauts
were intercepted by Air National
Guard F-16s while in R-5503. The balloons
were flying legally; it was the
fighters who were in the airspace early
and no NOTAM had been issued.
Airborne Conflict
Midair collisions between balloons
accounted for nine of the incidents,
with five reporting damage, and one
reporting an injury. Most balloon midair
collisions are of the “kiss” variety
where there is very little relative velocity.
Reports concerning damage and
injury were of the variety where the
lower balloon did not observe common-
sense rules in a crowded situation.
In one incident, the lower pilot
climbed rapidly into a balloon above.
The balloon below has the right-ofway
because of the lack of visibility, but
this does not allow the lower balloon
to climb rapidly. In an attempt
to preclude this type
of mishap, most balloonmeets
limit the climb
and descent rates to 200
feet per minute.
Six of the reports were
from air carrier pilots
who encountered balloons
in “their” airspace. The gist
of their reports was that they
were loath to share the airspace
and were surprised by the presence
of the balloons.
Conflict with Ground and Objects
Seventeen of the reported incidents
concerned flights into power lines, the
one incident which causes the most
fatalities in ballooning. In one third of
these incidents, the reporters stated
that the power lines were obscured in
trees. More than half reported minor
damage, and three reported injuries.
There have been other reported injuries,
including two broken ankles, to
passengers who were not wearing
proper footwear in a “ride” balloon.
Another ASRS incident record describes
one of the more serious types
of incidents when working with balloons
or airships—attempting to hold
the aerostat down by hanging onto a
line or the exterior of the basket. In
this instance, a crewman lost his grip
and fell, breaking an arm and an
ankle. No one should ever let his or
her feet leave the ground when
handling a lighter-than-air
vehicle.
They Don’t Understand
One of the problems aeronauts find
in almost every flight is the notion, “If
you’re having fun, or doing something
unusual, it must be illegal!” This
attitude seems to be pervasive among
unknowledgeable observers. One reporter
describes a balloon landing on
a boat in a lake after becoming becalmed.
The aeronaut and his balloon
were successfully
retrieved, only to find
themselves on the
evening news! Fortunately,
the local FSDO
was able to laugh with
the aeronaut over this.
In another incident, a
balloon was seen flying
through the tops of some
trees, an accepted practice to
slow forward velocity, and
then landed safely in a vacant
area. The observer was the local fire
chief who “called out the artillery.”

The Sky is Falling
Four incidents related to livestock
on the ground. One involved a typical
“balloon dog” that got upset, then
barked and upset its owner. In another
report, the balloon spooked some
cattle, and in another incident, the
balloon flew low over an aviary that
was not on the pilot’s chart. The most
serious incident was the alleged spooking
of a horse. Its rider was thrown
and suffered a broken arm.
