MLAT based data on FR24 is known for unrealistic speed/position 'spikes', but this a/c had ADSB, with taxi and t/o roll right on the lines. So I fear the worst, based on the (reliable) FR24 data until coverage was lost at 600ft, with 375 feet being the ADSB reported altitude when on the departure runway at this seashore airport.
