Blocked flight on FR24

[Hermolaus]

Just spotted a blocked flight on flightradar24.com. It's blocked literally: only minimal data, no ICAO hex code, and a callsign shown is... "BLOCKED"
http://www.flightradar24.com/BLOCKED/4cf1245
It comes from Seattle, Washington, US, flew over the ocean and currently (1310Z) it's over northwest Spain.
Any idea what could it be? TIA!

Looks like heading towards Madrid/Torrejon

Exactly. Should have landed ca. 1350Z.

Blocked flights are usually private aircraft (biz-planes). The owner can request that info which is sent out by there transponder can be blocked for sites like FR24. As far as I know, most of the times a "blocked" plane is from US origin.

Thanks for your replay, Michel N, and explaining things!
Two additional questions BTW:
1) Where to find over the net any (real peoples) logs/photos from LETO (Madrid-Torrejon)?
2) Where could the owners of these bizjets request blocking info on thier planes? Any civil aviation organization? (I don't think so...) Producer of the plane/transponder? (Neigher...) FR24 itself? (Maybe. If so do FR24 get paid for blocking private planes?)
