A Ryanair Boeing 737-800 flying into Dortmund (Germany) was struck by lightning during the approach on Sept 18, 2013. The aircraft landed safely but was taken out of service. A replacement aircraft was sent to continue the flights.
This is the second time in two years that this aircraft has been damaged by lightning. In January 2012, the aircraft was struck while landing in Sweden. That event caused damaged to the radome and the wing.
