IAS at first break up location was 144kts . It was not above Vne in the preceding manouvres ?
Breakup at approx where it got to 244 KIAS. I don't think they bothered with debris analysis so you'll just have to look at the wind and ponder. Witness statements mentioned in the executive summary but nought in the body of the report, they would have been interesting.
