Korean Air Boeing 747-8 HL7630 take off from San Francisco Airport RWY 28L

I just saw the information that this aircraft was retired from Korean Air and delivered to the Survivable Airborne Operations Center. I flew on this aircraft on October 6, 2016. It is still the only Boeing 747-8 I have flown on. I still remember it as the best flight experience I have ever had, including the aircraft, pilot skills, food quality, professional cabin crew, and transfer experience. The connecting flight (KE843 to Nanning) was just 45 minutes, but Korean Air provided the best experience for us from check-in at SFO, to the in-flight period, and during the time at Incheon Airport. I hope Korean Air can resume flights to Nanning someday.
