SkyLife 34, an Air Methods air-ambulance crew, has opened a base at Byron Airport on the far east edge of Contra Costa County. For now it mainly flies Kaiser patients; a county EMS agreement that would let it answer 911 calls isn't finalized yet.

Byron Airport doesn't get much notice. It sits two miles south of Byron on the far eastern edge of Contra Costa County, tucked in the wind shadow east of the Diablo Range, where gusts run 10 to 30 knots and student pilots come to practice crosswind landings. It's county-owned, uncontrolled, non-towered — a reliever field the FAA lists as C83 (external source, opens in a new tab), opened in 1994, with two asphalt runways and, as of 2021, 84 based aircraft: single-engine planes, a dozen gliders, one helicopter. On weekends the north end is a skydiving drop zone, and the Northern California Soaring Association teaches people to fly gliders off the same runways.

There are two helicopters based there now.

The new one is SkyLife 34, an air-ambulance crew run by Air Methods (external source, opens in a new tab), which opened the base this month (external source, opens in a new tab) and calls its helicopters flying intensive-care units. On board are a pilot, a flight nurse, a flight paramedic, and an on-call mechanic. The aircraft carries blood for transfusions in the air or on the ground, and a machine that keeps chest compressions going mid-flight. Its crew is trained for cardiac arrest, strokes, breathing crises, major trauma, and childbirth gone wrong. A regional director for the company, Vanessa Hayflich, framed the base in a written statement as a way to reach patients faster across the region.

What the announcement leaves for the fine print is who the helicopter actually flies for. Right now, SkyLife 34 mostly carries patients of Kaiser Permanente hospitals, according to Marshall Bennett, who directs emergency medical services for the county and spoke to Bay City News. It won't be a public 911 asset until the company's contract with the county is finalized; only then, Bennett said, can dispatchers send it on emergency calls inside Contra Costa.

That distinction matters most out here, because east county is where the distance is. Brentwood, Discovery Bay, Oakley, and Byron sit a long drive from the region's trauma centers, and the county's other air-medical base — Reach Air, a different operator — is across the county at Buchanan Field in Concord. A second base on the eastern flank shortens the map, at least for the patients this one is cleared to carry.

So the field changes a little. The drop zone and the glider traffic are still the reason most people come out to Byron. Parked among them now is a helicopter that exists to leave in a hurry.
