The conversation that led to the creation of the channel:
<ferram4|afk> So, I continue following references on supersonic wing stuff,
and I find a paper that tries to tweak linear supersonic flow to work for
high AoA, hypersonic flight.
<KinglyRedLion> the FUCK
<ferram4|afk> I love technical papers. ^_^
<KinglyRedLion> Why would you do high AOA hypersonic?
