I was on course at the return road just finishing my run when the Mariani rig came two vehicles after me I think.
While I was still all geared up sitting on my bike, I saw the liner go through the lights, and it was hauling the mail. The shoot ballast dropped, shoot blossomed, but he blew by my position still really fast. From my vantage point, it looked like just as he hit the backdoor cones he cranked the liner sharply to the left to keep her from going farther. Big ballsy move IMO to keep her from going farther. Kudo's to the pilot for making a sacrifice like that to keep her from going farther outside.
The liner then pencil rolled and got nose to back side about 130° in the air, then the body popped off. Even with my helmet on still, I could hear the stuff flying off and the awful sound it makes when a vehicle rolls several times. It looked pretty violent, but thankfully as said above he got out OK.
I will say this, that thing was movin' and sounded like she had a lot still left in her at the lights before they shut down. I hope they get her back together and straight, cause she will be a sight to see at B'ville for sure. Best to the Mariani's and hope to see you at B'Ville with her.
