Vortex storm
From Tardis Wiki, the free Doctor Who reference
While travelling forwards throughout human history, a trio of Dalek survey ships were caught in a vortex storm and arrived on Earth in 1908. Survey Ship Sigma and Survey Ship Delta collided and the latter was destroyed in Siberia, while Sigma managed to make it to Kent. Survey Ship Epsilon and its crew were on special duties, abandoning the Dalek Project in the process. (COMIC: The Dalek Project)
