Reading varoius reports, most seem to be focusing on a tire/rim explosion piercing the gas tank. One very good question on either this board or the Professional Pilots board, is to add Kevlar in the area where a burst tire/rim or compressor failure might cause rupture of the tanks. It would seem a lightweight fix to a problem that has already occured several times, this one with tragic consequences.
Beyond this, the piots love the plane.
