mike stehr Posted March 6, 2005 Share Posted March 6, 2005 "Immediate death of tissue 180dB - Jet engine at 1 foot" That would hurt. I was behind a pair of F-18's or something once at about 200 yards, with no hearing protection. Both aircraft took off at the same time with the backburners on, it wasn't very pleasant.
