The Coanda helmet

Coincidentally, the helmet was invented in 1910, the same year the jet engine was invented.

Hah! Those wags!
Some Xerxes Traianus put the tail on the nacelles! Goddamn plane flies great in retreats, I bet. Did François Marie help out on the plane too or did he just invent the centurions' helmets?
