When discussing Mike Pence's 737 over-run at LGA, with the report an unexpected bias was found in the FR24 ADS-B data. Their recording showed a hard 0 for a few hundred yards where the actual aircraft was still floating above the pavement.
The connection I am making is what if the EK231's assumed non-lift-off was also just an ADS-B mis-transmission, were they not airborne much sooner than indicated in the public domain? A bug or a feature to default for 'ground' below some small altitude. The FDM people already know.
C/A: congrats for the nice 2,200
