I have no idea what "Wilard" refers to....
I also don't see the connection between Ueberlingen and someone claiming to have witnessed an airprox whilst on the ground in Dulwich.
I have tried to be nice in my answers... but to be honest I have spent so much of my career being told by people that "two aircraft nearly crashed". Add in the sensatioanlist wording an dthe "I should know, I've seen aircraft before" and you will hopefuly understand why we get just a wee bit sick of this...
Bringing in a completely unrelated accident doesn't help anyone
