The design figure was actually in the low to mid 100s in mph, below EF3-EF5, which seemed logical given the understanding of tornadoes in the 40s. The structure was designed to actually lift somewhat and remain intact.
I would have doubts about the windows remaining intact if struck by debris at high wind velocities. But that's just MHO, not based on any actual data.
