Bolted down AND paved over
Paved over you say?
How did they then so quickly determine for P2 all the over "paved over" covers were secure after only destroying three multi-million-dollar cars?
Other than claims here, I haven't seen anything to confirm they were supposed to be bolted down and/or paved over.
The earliest pic post-accident of the cover area doesn't indicate any obvious bolting or shattered pavement that would have covered the cover, IMO.
Seems welding has been an adequate decade plus proven solution.
