I want you to handle any investigation I am involved in, Wiz.

If it was high enough energy to either burst or deflate 12 tyres it would normally be classified as "high" or even "severe" risk in a safety analysis.

The tyres didn't "burst", they deflated because the fuse plugs did the job they are designed to do.
Yes in the video they did. You have video of this event?

Not saying it didn't happen, just saying you don't know it did happen.

The fusible plugs are placed on the rims, near the brake assembly in order to react to heat generated from the brake pack. If the heat in the tyre is not generated from the brake pack (i.e. it is generated in the tyre itself during long taxi operation for instance) then the fusible plugs more often than not won't operate (as rubber is a poor conductor of heat, sufficient heat doesn't reach the plug) and the tyre will burst.
