One of the more interesting things we did back in that time period, happened to one of our pipeline companies which is similar to what is happening in the gulf now, but on a much smaller scale. It seems that one day the folks that controlled the shipment of petroleum products in the pipelines got their orders for the day mixed up, and sent jet fuel and diesel oil in the same pipeline, but in opposing directions. The pressure was so great, that the pipeline erupted and forty thousand gallons of number two diesel oil dumped into a small seven acre fishing lake in Kansas which was near the pipeline.
Because it was hard to see out of the helicopter, when I made my approach to the lake, I decided that when I could see waves made by the rotor downwash, I would decrease my decent and establish a hover. This almost became a disaster. Actually the waves would not appear until after the helicopter is in a hover. On the decent, I misjudged and actually sank the helicopter in the lake almost up to the floor of the helicopter. When I realized what I had done, I instantly raised the helicopter out of the water and luck was on my side that day. The good old Lycoming engine kept on running. When I returned to the airport, the mechanics made a thorough inspection of the helicopter and nothing was found wrong.
