The article provides an explanation of stronger than expected by the Author
Draconids 2011 activity basing on the assumption of unusually high density of 1900 trail of
the comet 21P Giacobini-Zinner. Also, a revised prediction for Draconids 2014 is pre-
sented, which should also be caused by 1900 trail. For this prediction a ‘‘vertical trails’’
approach is used. This approach is described in the article.
