Yeah, you're probably right. The prosecutor press release makes a point of talking about his experience as a pilot and a skydiver, so "special skills" might apply. But the big-ticket accelerator is (b)(1)(A), and I think you're right that it can't apply to him exfiltrating and cutting up his own airplane.
Turns out yes to the extensive planning enhancement, as well as an aggravated role enhancement. But no to the harm/substantial interference/special skills enhancements. Details in uncle/aunt comment (is that a term?) now that I've found the plea agreement.
Thanks! I found it in the California Central District PACER instance by searching for his full name (both the court and name given in the DoJ press release) - I suspect the national index syncs only so often with the individual PACER instances and it just hasn't got this case yet.
