From the same Herald article (please see post below):
The stakes are high: When 50 mph wind gusts caught operators of a similar balloon ride by surprise three years ago in Baltimore, 17 people on board were trapped for nearly two hours as the gondola thrashed in the air and hit a nearby building. The ride -- made by Lindstrand, the same British manufacturer that sold SkyLift its balloon -- never reopened, according to media reports.
Less than seven days later, a tourist fell to her death out of the gondola on a similar Lindstrand tethered balloon in Lucerne, Switzerland, when it was caught in an unexpected wind gust, according to a Swiss government report. . . .
