Well, the MD-11 that bought my on line car parts to Auckland yesterday must have had some hours on her. 26 years old according to Flightradar and she didn't get a lot of ground time as FDX 75.
I know the record is presumed to be a B747 (long sectors,lower cycles etc) but could a UPS or Fedex DC-10/MD-11 be up for the challenge?
