A 40' dive is nothing. One car is at 60'. Also no big deal. What is so dangerous? They plan to touch them. If only 2 divers are down there, attaching bladders to the frame, out-fitted with oxygen tanks, hydro-hoist. That will create a cloud of silt, rendering the diver blind. Visibility will go from 8" to ZERO INCHES. It isn't black at that depth. It's dark or darker green. It will take hours to restore it to 8". So you have to get out of the water and wait. There is no glass in any of those cars - gone. Bring Em Up. There will be no physical evidence of anything. If this operation is supported by LE, why wasn't the dive team given the GPS numbers? Why did this new diver have to locate them with infra-red cameras? Everyone in LE (3-5 jurisdictions) has the GPS locations. Equusearch does. The diver that mapped them does. I understand team "Operation Bring Em Up" are doing "practice dives" blindfolded. I don't understand why. Do a night dive. Turn off the sun. Bring under-water lights - a timing-light. Take a photo essay of each car - 100 frames of each car - enough to establish make/model/year. Pray for a VIN#. That is a full day PER CAR. Compare them to the records that will identify the owner...No! wait, they won't have any records. I guess they can put the facts on the news and turn the public loose. OR figure out what, if any, vehicle is of interest to our case before you go down there, and leave the other two alone - for those families to make their own decisions. That's the problem I have with the approach of "Operation Bring Em Up."
