Someone in a hurry
Many years back I used to monitor area and terminal radar at Auckland when a domestic 767 checked in with the area controller at Ohura (several hundred miles from touchdown)
ABC767: "ABC767 with you FL XXX, any speed restrictions?"
Area: "ABC767 identified, you will have to ask the next sector about the speed"
Clearly the area controller passed on the speed request as when the 76 checked in with Terminal (50 miles from touchdown) I heard;
ABC767: "ABC767 with you descending to 11 thousand"
Term "ABC767, cleared to the VOR, 900 knots, descend 6000' "
ABC767: "Roger, going supersonic, descending to 6000' "
Made me smile.
