<VV> Off topic, re NOS and fuel

[Ken Klingaman]

Talk of NOS and gasoline reminded of the hopefully included book. It maybe of interest only those interested in liquid propellant rockets. The work was done on the range next to to the one I work on.
On pencil gages, there is a pressure gage used for measuring blast pressures that happens to look like a big pencil, hexagonal cross section and pointed. Local calibration is done with C-4 explosions at known distances and amounts.
