FAI has received a new record claim simultaneously breaking both
World and European simultaneously by 4 pilots. An out-and-return distance of
302,11 km was covered by the 4 leading pilots of Slovenia: Bojan Gabersek,
Primos Susa, Jost Napret and Dusan Oroz.

The current European record of 264.05 km set in 2011 belongs to Arduino Persello,
Italy. He is also the holder of the World record of 282.4km set in 2012.

We have asked the claimants to introduce themselves and tell us how it was.
