Thanks to Airbubba for the data, which I subsequently de-duplicated and harmonized
A closer look at the final ten minutes, starting from the transition at FL100 - altitude (orange) and inferred ROD (blue histogram)
Clarky, clearly a steep plunge (4 ~ 6,000+ fpm) to capture the ILS gs. At no point did this resemble a stable approach
P.S. Exactly four minutes from FL100 to "touchdown", 90 secs from FL80 to 2,000' (= 4,000 fpm).
Brisk.
