We landed in Carrizozo about a month ago. Lets just be kind and say the runway needed a "trim". There was a good amount of up to 3+ feet tall grass tufts growing randomly through the cracks of the asphalt along most of the runway. Was it like that a week ago? I don't know, but my guess is it's probably likely. Bill, the airport manager and great guy was having some health issues and, if I had to speculate, wasn't aware of the the tall grass on the runway (his health issue is pertinent in this case but I'm going to give him HIPPA and not divulge it here). I'm not saying some scruffy grass caused the crash but It certainly would have been a distraction departing F37. It was for me a month ago.
That area (and much of New Mexico) is susceptible to powerful dust devils which may or may not distinctly visible. There were at least two that were distinctly visible close to the airport the day we departed. Could there have been more stealthy ones? Perhaps. It's likely pilots would recognize a majority of them, but if they were concerned about the tall grass on the runway might they have not? I've been in and out of that airport a handful of times. It's not a particularly challenging airport for takeoffs even on hot days with proper procedures but an added anomaly could escalate a takeoff threat.
Our New Mexico dust devils can be formidable. If there was one on or near the departure end of the runway that would likely have a considerable impact on aircraft performance.
I'm just speculating here but if you are not familiar at flying in the arid west in the summertime realize that those mini-tornados can be a threat. I'm very glad the occupants are fine. Hopefully they are on MS and can give us a first person account.
Watch out for those dust devils on departure (and arrival).
