B1 250 KPH + Model tethered hydroplane 2017 world championships Bulgaria

Hitting atoms in space approaching light speed turns them into gamma radiation, you turn into jelly and die. https://en.wikipedia.org/wiki/Interstellar_travel https://www.astro.umd.edu/~mil....ler/teaching/astr380 https://www.projectrho.com/pub....lic_html/rocket/slow

Yeah - notice how it does not touch the water nor aim into the sky - once it gets going.... I suppose that still counts as a hydroplane... It's still pretty fucking fast though..... BUT with these sports, they have been doing them for many years, and all the tracks have been designed to contain most of the bits, most of the time... They just use chicken wire around the racing planes, and the tethered car tracks, have a physical barrier around them as well as a chicken wire ??? fence. The thing is that with the hydroplanes, once the tether breaks, the whole system becomes dynamically unstable and rolling sidewards would induce it sort of ploughing into the water, which stops almost anything like a brick wall.. The only have a surface based wall, around the lake, and no fence to protect the spectators.... So shooting off the water - up into the air and hitting the spectators must be exceptionally rare or basically non existant.

if it was going fast enough the tether would no longer be able to hold it, even if the tether was made of spider silk.... would be interesting to find out what kind of damage it might do to a static object....
