Also, I probably wouldn't go retarding the thrust levers at 30ft as a matter of course, I'm sure Parrabellum didn't mean you to transfer 747 techniques onto the 73 but I just thought I'd mention it in case you took it literally and thumped it on again next flight!
Spot on
Framer!
MRBH, those were 747 numbers, to be adjusted to the 737 as appropriate, though you wouldn't flare much below 10', I would have thought?
The best advice is to put the whole episode behind you and move on, you know from previous experience that you can do a decent landing and yes, we have all thumped them in at least once. One day you will laugh at what the pax said and tell the story in the bar.
