Atlantic 404 Sniffer

From Tardis Wiki, the free Doctor Who reference

The Atlantic 404 Sniffer was a coastguard aircraft with remote sensors capable of detecting oil beneath the surface of water. In 2008, a 404 Sniffer was deployed to spread a powdered bio-remedial agent across Cardiff Bay, dissolving a rapidly-spreading and potentially sentient oil-like substance. (PROSE: Black Water)
