Supporters of the chemtrail conspiracy theory occasionally claim there were strange echoes on the weather radars of meteorological services which seem to be ''ghost clouds''. On July 19th 2005 e.g., the radar screens of German Weather Service (DWD) showed a small compact cloud formation at the North Sea coast of the Netherlands which looked like rain. Within two hours the radar showed a 300&nbsp;km long cloud strip, reaching from the East Frisian Islands down to the northern Ruhr Area. But at the same time no clouds were visible, neither from the ground nor on satellite images, nor anything that might have looked like a mass of contrails. In this case, as well as in similar ones, ''chaffs'' (''Rapid Bloom Chaff(RBC))'' had been dispersed as part of a military exercise. Chaffs are small metal threads that reflect radar waves and disturb radar<ref>http://www.spiegel.de/wissenschaft/mensch/0,1518,445727,00.html</ref><ref>http://www.presse.uni-karlsruhe.de/6428.php</ref>. Supporters of the chemtrail idea cannot be talking about chaff. Even they do not claim a correlation between supposed chemtrail sightings and strange radar echoes.
