I was surprised on Friday night coming back into SFO to see KLM still at the A gates. Looked like a cowling was open on one of the engines. By the time I got outside, it had been moved away from the gates to where Qantas is usually parked during the day when not headed to Vancouver.
Saturday I was near the airport and noticed KLM was still there. Flightaware indicates it left as 608 around 7:30 Sat. night.
What happened with the pax? Was it an engine issue? It was cool to see the big blue hanging out at SFO.
