You're not repairing space shuttles over Thanksgiving break? :O)
No, it doesn't. Doesn't sound like the kind of thing you'd accidentally come across. That makes it a hit. Not too subtle to use something that if/when found, couldn't realistically be anything other than a hit. A hit by someone with a lot of resources behind them...
Nyet.
