Fatal Crash near Henderson, NV
« on: May 19, 2016, 10:56:15 AM »
On April 30th, there was a fatal crash near Henderson NV, killing the pilot and one passenger.

The details are well covered in news articles like this one

I pulled the audio, and eliminated big sections of silence and unrelated audio traffic.
The result is about 11 minutes, extracted from nearly 3 hours.

After more than two years since the accident, the factual report is published.

The link should be:

Some surprising parts of the report:

drug testing identified 9.4 ng/ml of Tetrahydrocannabinol (THC) in the pilot's cavity blood; THC was also
detected in the lung, liver, and brain. In addition, 10 ng/ml of tetrahydrocannabinol carboxylic
acid (TCH-COOC) the active metabolite of THC, was identified in the cavity blood; it was also
found in the lung, liver and brain. TCH is the primary active metabolite of marijuana and may
impair mental and/or physical ability required for the performance of potentially hazardous
tasks, such as flying, driving, and operating heavy machinery.

...the persons being carried for compensation or hire are not interested in flight training. It is therefore unlikely that the purpose of these
flights would be student instruction. Furthermore, because the flights you describe are
introductory flights, it is unlikely that the persons would be receiving flight training for the
purpose of satisfying a training requirement outside of part 61."

To give a little colour around the THC thing. I take a tincture solution in the morning for pain that would put me a little shy of 4 ng/ml, I'm totally safe to operate vehicles (although I don't). If I smoke a pretty big joint, I'd be at around 12 ng/ml - additionally, the decline of THC in the blood is pretty rapid.

It's pretty hard to know for sure, but if I had to guess I'd say the pilot smoked a fair sized joined either directly before flight or maybe even during given the closeness of the carboxylic and non-carboxylic.
