Thankfully, no one got hurt; but we had a potentially VERY dangerous situation on our hands. How to salvage our AvGas quickly and safely, while also planning on getting the truck and tank out of the swamp.
Thankfully, I work with an amazing team of very talented and ingenious men. With a lot of teamwork, a Caterpillar excavator, and lots of sweat, we had the tank sitting back on top of the truck and they drove off about 36 hours after first arriving. Normally the process takes less than three hours to offload the fuel. Now, we still have a huge hole to repair in our driveway, but that will get addressed when the dry season comes in a few more months.
