- History of the Flight:
On August 13, 2025, at about 2300 local time, a Beechcraft M35 Bonanza, N951T, registered to an airline transport pilot out of Frederick, Colorado, was destroyed when it was involved in an accident near Des Moines, New Mexico. The pilot and passenger sustained fatal injuries. The cross-country flight originated from Pueblo Memorial Airport (PUB/KPUB), Pueblo, Colorado, at about 2210 LT, and was destined to an unknown location (at the time of this writing).
According to preliminary automatic dependent surveillance-broadcast (ADS-B) data, earlier in the day, at about 1940 LT, the airplane departed Erie Municipal Airport (EIK/KEIK), Erie, Colorado, on a flight to Pueblo. The airplane landed at 2050 LT. About 1h20m later, the airplane departed runway 8L at KPUB and entered a climbing right turn to an inflight cruising altitude 8,000 ft. The airplane was tracking south and the flight appeared uneventful.
At roughly 2253, the airplane's track stopped about 17 miles north of the Sierra Grande on both the Flightaware and ADS-B Exchange sites. However, Flightradar24 continued tracking the airplane south. At roughly 2255 LT, the airplane descended to an altitude of 7,500 ft. At 2258 LT, the airplane initiated a climb, which stopped at 7675 ft when it flew into the Sierra Grande, an extinct stratovolcano that has an elevation of 8,723 ft (see figure 1, 2, and 3).

.SHORT TERM...
(This evening through Thursday night)
Issued at 1133 AM MDT Wed Aug 13 2025
A downtick in shower and thunderstorm coverage with slightly above
average high temperatures is expected this afternoon and evening
due to the 593 to 594 dam upper high centroid moving from north
central AZ to western NM. Isolated coverage is expected across the
north central and Sacramento Mountains with scattered to numerous
coverage across the Gila Mountains near Glenwood and Pleasanton where
higher PWATs of around 0.9 inches will be present. Some of these
showers and storms could move into the nearby highlands resulting in
gusty and erratic winds at locations like Raton, Las Vegas and
Gallup. Any shower and thunderstorm activity in the state will taper
off after sunset with lingering mid level clouds across western and
central NM heading into the dawn.
The 592 to 593 dam upper high moves east to over the NM, CO, OK, and
TX borders Thursday afternoon. This along with a trough entering the
Pacific coast will allow for a traditional monsoon flow to setup
across AZ with far western NM on the eastern edge of this flow.
Scattered to numerous showers and storms will favor the mountains
and nearby highlands along and west of the Continental Divide, where
PWATs will be around 0.7 to 0.95 inches, with isolated to at most
scattered showers and thunderstorms across the north central
mountains and Sacramento Mountains. High temperatures will be 5 to 9
degrees above average areawide. Showers and thunderstorms taper off
around sunset with activity lingering longest near the AZ/NM
border
