Paraglider and Hang Glider Collide Near Aspen Mountain, Nearly 3 Dozen Rescuers Respond

A paraglider and a hang glider collided in midair near Aspen Mountain on Sunday, leaving both pilots injured and prompting a rescue operation that pulled in nearly three dozen crew members. An Aspen Mountain ranger made contact with the two injured people shortly after the collision, according to a sheriff's office release, and Mountain Rescue Aspen crews were dispatched to reach them on the mountain.

One of the injured pilots suffered only minor injuries and was evaluated by paramedics at the scene, according to The Denver Post. That pilot declined further medical care, walked uphill to the road under their own power, and did not require transport. The second pilot's condition was described as unknown, and that person had to be rescued from the mountain using a stretcher and rope system before paramedics took them to a hospital.

The rescue drew a sizable response for a mountain accident: sheriff's officials said nearly three dozen crew members took part in the operation. Both the patients and the Mountain Rescue Aspen crews were out of the field by 1:22 p.m. Sunday, according to the same account.

A Volunteer Force Built for Pitkin County's Backcountry

Mountain Rescue Aspen is an all-volunteer, nonprofit organization with roughly 50 active members that handles about 100 search and rescue missions a year across Pitkin County, per the group's own account of its operations. The organization relies on public donations and grants rather than a dedicated tax budget, and it's reimbursed for equipment and operational costs through Colorado's CORSAR Card program, which channels state funds to volunteer search-and-rescue teams without billing rescued individuals directly.

For missions that exceed what ground crews and rope systems can manage, Pitkin County authorities can call in Black Hawk helicopter hoist crews from the High Altitude Army National Guard Aviation Training Site in Eagle County, according to the Colorado Search and Rescue Association. Sunday's rescue was carried out with a stretcher and rope system rather than an aerial hoist.

Officials Renew Calls for Separation and Communication

In the aftermath, the Pitkin County Sheriff's Office advised that mountain aviation participants should carry reliable communication and safety equipment and maintain appropriate separation from other aircraft. The advisory echoes guidance the office has repeated after prior backcountry aviation incidents, emphasizing multi-channel radio use and visual separation, particularly in summer months when strong thermal updrafts draw heavy mid-morning air traffic to local ridgelines.

Federal rules already require unpowered ultralight aircraft, including paragliders and hang gliders, to maintain vigilance and avoid creating collision hazards under 14 CFR § 103.13. Because these pilots don't carry FAA airman licenses or transponders, sightlines and radio contact remain the main tools for avoiding midair conflicts. Industry guidance from the United States Hang Gliding and Paragliding Association also spells out right-of-way rules for gliders approaching each other head-on, with lower-altitude aircraft generally holding priority over higher ones.

A Regional Pattern of Free-Flight Emergencies

Aspen Mountain has hosted commercial tandem paragliding and flight instruction since 1990, when Aspen Paragliding was established in cooperation with local mountain managers and the U.S. Forest Service, according to Frias Properties. Aspen Skiing Company permits paraglider lift access only on Aspen Mountain at designated launch sites and bars landings within ski area boundaries, with paragliding launches forbidden entirely on Snowmass, Highlands, or Buttermilk.

Sunday's collision follows a string of free-flight accidents across Colorado and beyond this year. Mountain Rescue Aspen's own 1,000-foot tumble down Maroon Peak rescue in May showed the scale of technical operations the group regularly handles, while a paraglider crash near This Is the Place left another pilot hospitalized in June, as per Hoodline. Elsewhere in Colorado, the Alpine Rescue Team was paged in June for an injured hang glider pilot on Lookout Mountain in Jefferson County, underscoring how frequently the state's volunteer teams respond to downed free-flight pilots.

Aspen has seen serious free-flight accidents before. In October 2021, a solo paraglider pilot survived a 100-foot fall onto the slopes of Aspen after an equipment strap tangled his emergency parachute handle, a crash that required a three-hour carry-down by ground rescuers and left him with spinal fractures before he regained full mobility. It remains unclear from Sunday's release whether the paraglider or hang glider pilot involved was flying recreationally or as part of commercial instruction, and the exact altitude and conditions at the moment of contact have not been disclosed.
