ABGD - you think he may not have noticed?
Take a look at the end photos on this site, where some youths are standing by one they built.
Rans Build Pages [This aircraft has nothing to do with the incident, it is just a good photograph]
I don't know the clearance under the wing of a Rans 6, but I do know that youths are rarely available equal to the height of the van roof - 2225mm. The contact point was not on the wing tip, but approx 15cm inboard from there. You will appreciate the angle of bank that creates for the Pilot, which continued for the length of the van. When the wing "fell off" the van rear, the Rans lurched to the right so hard I thought the Pilot was pulling over. The Rans wheels left the taxi-way and the Pilot corrected for that and rejoined.
The impact left red dye from the Dacron cover along the edge of the van roof.
The pilot "did not notice"? If that's true, how can he possibly fly the aircraft! His sense of balance is shot, as is his observation of the horizon / bank angle.
It seems likely that you will read more about this event in later months.
