clarification . . . . . . . .
to both today's contributors:
I learned today that there was actually some nasty weather around at the time of the accident involving G-CFAZ. Apparently some nasty dark stuff, practically down to ground level, especially to the east of EGCB, and towards the Pennines where the accident took place.
I was flying at the same time, but we were to the west of the local area and we saw nothing we'd regard as threatening.
The reference to "in-flight break-up" did not mean that it was spontaneous, but rather was perhaps a consequence of inappropriate or ill-advised speeds or G-forces. It would not be a reason for groundings or mandatory mods to others of the same type.
Sorry if I did not make this clear previously.
