Indeed FR24 it does not seem to show any airborne activity prior to departure of the flight to OOL. On FR24 (and Flight Aware) such an event at a major airport with lots of data feeders nearby would generally show up just like a rejected takeoff or aborted landing - as a continuous trail incorporating all air and ground movements by the aircraft. In fact if an aircraft returns to the gate, the previous excursion will often still be appended when the flight does eventually take off, sometimes hours later.
