Not in RPT service at the time, as no pax on board, plane being towed it seems. That tow driver will be certainly looking for new job.
There's been a couple of ground incidents lately at Changi, last one was a landing gear collapse during inspection at gate. Neither this or the last one involving passengers of course, but ground service staff seem to be not operating to the standard needed .... just can't take airplanes down to the panel beater and get them fixed.
