I came across a âboothâ (sorry) for Banner Ups/Budnick Converting, which featured a video of a vinyl banner placed in a wind tunnel and exposed to 100-mile-per-hour winds (watch it here: https://youtu.be/L55Jy82edcA). Videorecorded at the National Institute of Aeronautical Research, it was at the time (2017)âand may still beâthe strongest banner wind survival ever documented, making it up to 108.2 mph before failure.Â
