Sure, most commercial aircraft were probably broadcasting their position etc. via ADS-B, the question was just if they were picked up by a Flightradar24 receiver. Also, I'm not sure what the threshold is for Flightradar24 to consider a flight "tracked" - probably at least the takeoff and landing? So (to use the same example) if there was a receiver near the larger city in Indonesia where the flight originated, but not near the remote airstrip where it landed, it probably isn't considered tracked?
