On 8th June I was logged at ON4KST chat in passive mode for Es monitoring and then I saw DX-cluster spot from EA8AVI, that he heard on 2m UT5JCW 539 via Es. Everybody thought that it's joke, because the QRB would be 4688km. However after logging at EA VHF chat I saw there communication between Pedro, EA8AVI and Mariano, EA3EDU, that Pedro really heard Serge UT5JCW very well and then his signal disappeared. UT5JCW claimed that he used during his CQ only 50W! an lately heard EA8AVI for 3 seconds however too short for QSO. The reason of this propagation would be the combination of Es or MS and Tropo above Mediterranean Sea. By the way the same signal path was used during actual World 2m Es record between former UO5 (now ER) and EA8AK on 12th August 1981 with QRB of 4391km. If you don't believe, you can ask to DK5OX, as he was UO5OGX :-)
