The deaths of Michael Kennedy and Sonny Bono were in many respects typical of mortal skiing accidents: The victims were both confident skiers doing risky things on slopes not considered particularly dangerous.
'The deaths of Kennedy on Dec. 31 at Aspen, Colo., and of Rep. Bono (R-Calif) on Monday at Lake Tahoe, Calif, generated a surge of public concern over safety on the slopes. But experts said yesterday that, overall, snow skiing is a relatively safe sport and is probably less hazardous now than 25 years ago.
"Most serious injuries happen to experienced skiers while they're skiing on easier terrain than they are used to," said Jeffrey Hadley, an injury epidemiologist at Johns Hopkins University Those skiers are often overconfident, going at high speeds and not concentrating as intensely as they would on more difficult slopes, said Hadley, a former ski instructor.
In addition, both celebrities died in the late afternoon, which in the view of experts is a critical time.
"A lot of these injuries happen later in the day," said physician and epidemiologist Julie Gilchrist of the federal National Center for Injury Prevention in Atlanta. "It's safe to quit before you get exhausted."
However, skiing and snowboarding contribute to few fatalities in the United States. On average since 1984, skiers have made slightly more than 50 million visits annually to U.S. ski slopes and an average of 34 people have died each year, according to data compiled by the National Ski Areas Association, a trade group representing 330 resorts that account for 90 percent of America's skier visits.
By comparison, approximately 800 Americans are killed every year in bicycle accidents and more than 700 in recreational boating accidents.
As for serious but nonfatal ski injuries, "I don't see any evidence that they have increased" since 1970, said Jasper Shealy, head of the industrial and manufacturing engineering department at the Rochester Institute of Technology.
Shealy, whose specialty is the study of how accidents occur, has reviewed ski injuries extensively for more than 25 years. The typical profile of a fatal accident, he said, is one involving a male, in his teens to mid-thirties. Males are involved in 85 percent of all ski deaths.
"It's generally an intermediate to expert skier," he said, on an intermediate slope, usually "out at the edge of the trail going from 25 to 40 miles per hour." Typically, the skier loses control and "when you slam into a tree at that speed, there's not much hope for you," Shealy said, "and a helmet probably wouldn't help."

Head and spinal injuries of the sort reportedly suffered by Kennedy and Bono make up the largest category of serious injuries, according to the data from the National Ski Areas Association. 'These account for about one-third of the 35 to 45 catastrophic but nonfatal injuries at U.S. ski resorts every year. The association defines a serious injury as one that results in paralysis, severe head injuries or coma, or severe internal injuries.
The Kennedy and Bono deaths, Shealy said, were most likely a "random coincidence" and do not represent any kind of a trend. Gilchrist agreed. "Over the last few years," she said, "skiing has been safer."
According to the National Injury In formation Clearinghouse, part of the federal Consumer Product Safety Commission, an estimated 120,000 to 130,000 injuries of all kinds result each year from snow skiing, ranging from a recent high of 141,302 in 1994 to 108,385 in 1996, the last year for which data are available.
The American Journal of Sports Medicine published a study in 1994 of ski injuries over a 22 years at Vermont's Sugarbush Mountain. The 8,023 serious injuries included many more lower-leg injuries in the early years and many more serious knee injuries in the latter part of the study period. The incidence of upper body injuries remained constant.
Shealy of Rochester, one of the study's authors, said yesterday that this year an estimated 15,000 to 20,000 skiers will suffer knee injuries, at a total cost of $400 million in medical bills.
Shealy and co-authors Robert Johnson and Carl Ettlinger of Vermont attributed the decline in fractures and lower leg injuries to design improvements in ski boots and bindings. Ettlinger said yesterday that updated equipment has changed the way people ski, and some times that means they head downhill with more speed, but less experience.
According to the National Ski Areas Association data, nationwide fatalities increased about 3 percent during the 1996-97 season compared to the previous year. In the 1996-97 season, 36 skiers or snowboarders died, the trade group reported recently, for a death rate about 0.69 per million skier days. In previous season, 35 died.
But the highest recent death rate recorded in 1994-95, when 49 persons died for a rate of 0.93 per million days. Since 1979, according to figures, the total number of skier days has averaged slightly above 50 year. Over the past 13 years, the annual number of fatalities has ranged from 24 to 49, and the rate from 0.48 death million skier days to 0.93.
"There are risks inherent in the sport," said Julia Carlisle, a spokeswoman
for Killington in Vermont, the biggest ski area in the East "In fact, that's why
people participate--to get a little thrill."
