[TheForge] Upside down Press - oh what a tangled web weweave

[James Binnion]

H.P. hydraulic leaks are scary for sure. Was in the control room of a  
submerged submarine when a bolt on an isolation valve body failed on  
3000 lb hydraulics to fairwater planes (sail planes). It filled the  
control room with a mist of hydraulic oil in an instant and dumped  
about 50 gal of oil in the room in not to much longer. Scared the  
crap out of all of us. Damn lucky we did not have a fire or explosion  
given that finely dispersed mist. It was so thick you could hardly  
see across the room.
