Federal Authorities are investigating the crash of a banner plane that went down in southern Delaware on the 4th of July. The plan reportedly crash-landed upside down in a wooded area near Rickards Road between Roxana and Millville at just after 3:50 p.m. on Thursday. The pilot, who had taken off from Bunting Field in Berlin, Maryland, around 3:00 p.m., survived the crash, reportedly without serious injuries. The plane went down after flying along the beach for almost an hour.
