Ask any Chinook Pilot about Hydraulic Leaks in the Flight Control Closet on the Port Side of the Cockpit Companion way! Fight controls at 3000 PSI and Utility System pressure lines at 2500 PSI...makes for an interesting time.
Likewise...the Forward Transmission Oil Filter blowing off and the Sound Proofing not being installed under the Tranny gets interesting in the Cockpit as well.
What is more impressive is a fuel leak back aft when one of the 400 PSI lines with a diameter of about six inches lets go....(at least that is what One would think when a Jet Fuel Niagara Falls happens).
