The question is, if it was about noise, whats worse? A TOGA go around from 500ft or an idle reverse landing?
The general public (the ones who vote in our pollies) don't understand the subtle difference between idle reverse landings and TOGA go-arounds!
They just don't want aircraft landing or taking off during the curfew! The law is there to re-enforce that. No politician will risk their seat and go against that!
