I was too loose with my phrasing. I didn’t mean a person had to go down 5,000 feet. But I think you over-simplify it. Explosive devices with a guidance system are sophisticated devices.
An unidentified vessel would not be able to get very close to the rig without notice.
Google :˜make your own submersible” you would be surprised the “off the shelf” technology out there and don’t forget many of the countries that hate use send lots of people here to study and engineering is what a good portion of them study.
The SWAT Teams were sent for a reason and I don’t think they are holding “Tea Parties” on oil rigs and I don’t theink the are out there to scrub oil of sea guls!
What good is an explosive devices going to do except spread the leak out wider?
