Thanks to jlemon and WHBM for adding the details on LSI. I suspected WHBM knew the spot when he originally deferred his response.
I too remember the multiple fatality, which occurred long after we moved back to MSY. Traffic was fairly intense even in the late 70s and the waiting areas at LSI were almost surreal with all of the pax suited up in hot uncomfortable full-body survival suits for trips offshore. I had no problem paying attention to safety briefings!
