Definitely a small, homemade flying wing (white foam) with a GWS 50 (or 75?) ducted fan. There appears to be the remnants of a speed control and/or micro receiver there too.

I'm guessing that if you were using this type of stuff, you might have saved youself $10 to $12 when you found it. Other than that, sorry.... [&o]

New prices: GWS 50 ducted fan and motor - about $18. GWS micro receiver with crystal - $28. Mini ESC - about $15.

The stuff looks pretty beat though, that's why I'm saying $10 to $12.
