Hi "cleared to land"!
Sorry to interfere, but assuming either thrust lever was not closed and/or
flaps less 25
there would be no landing gear configuration warning!
The warning what they should have had comes from the GND PROX WARNING,--TOO LOW GEAR!
My respect to your flight safety office!!! Thatīs the way occurences like
that should be handled.
Demotion in such a case would be holy stupid!
