CFC3918 landet sunday night ( 23:20 LT) in Cologne. all CC-150 in the last few month fly with CFC4XXX call sign, so someone know what is CFC3918 ? (C-130 or C-17 ? )
This was flying at FL330 so usually a bit higher than the CC-130s fly which is generally at FL220-FL280
This was either a CC-177 (C17) or a CC-150.
The callsign suffix confused me too, as this is usually a CC-130H but going by the Flight Level, it seems a bit higher.
