Hi Andy,
No, I am not sure at all of the aircraft type.
The witness I met (over 80++) mentioned to me “FW190” but I don’t trust very much his aircraft knowledge.
Then, I had other comments it could be JU88.
He115 ? I don’t think so, I am in the Toulouse area and I don’t think we had He115 flying here.
So, I do not know the aircraft type and I wish I could identify it with certainty.
All best
Gilles
