An Ex Rocket Man's Take On It: About Hypersonic Vehicles
There is a formal definition: “hypersonic” is that speed at which the shape of the shock wave system about the vehicle no longer changes its shape appreciably as flight speed increases further. The speed at which that happens depends upon the shape of the vehicle. For “pointy” shapes likes missiles and aircraft, it is just about Mach 5, or a velocity that is 5 times the speed of sound. For really blunt shapes like space capsules traveling heat shield forward, it is just about Mach 3. Those two values are the rules of thumb for “hypersonic”, for those two classes of shape.

Bacterial and fungal isolation from face masks under the Covid-19 pandemic
We surveyed 109 volunteers on their mask usage and lifestyles, and cultured bacteria and fungi from either the face-side or outer-side of their masks. The bacterial colony numbers were greater on the face-side than the outer-side; the fungal colony numbers were fewer on the face-side than the outer-side. A longer mask usage significantly increased the fungal colony numbers but not the bacterial colony numbers. Although most identified microbes were non-pathogenic in humans; Staphylococcus epidermidis, Staphylococcus aureus, and Cladosporium, we found several pathogenic microbes; Bacillus cereus, Staphylococcus saprophyticus, Aspergillus, and Microsporum. We also found no associations of mask-attached microbes with the transportation methods or gargling. We propose that immunocompromised people should avoid repeated use of masks to prevent microbial infection.
