This almost certainly refers to the UK K21 incident in 1999. I don't
know about the Soaring article, but the UK Air Accident Investigation
Board report is at:

http://www.aaib.gov.uk/cms_resources...pdf_500699.pdf

Unfortunately the diagrams and pictures which were accessible when the
report first came out are not included in the .pdf.

Hello all in US-gliderland,
Some time ago, there was an interesting article in Soaring about a
glider being struck by a lightning. I seem to remember a photos of
scourched sneakers, a blown out canopy and other damage. Can anybody
tell me which issue of Soaring this was or if this article is available
online?

Thanks,
