California's "John Wayne Airport in the US is probably the world's most noise -sensitive airport and the whisper jet is the only aircraft that has been approved to operate in and out of that airport", he said.
As someone has already pointed out, this is wrong. Many other jet types can and do operate from SNA all the time. What is true is that, when the 146s were introduced at SNA, they were cleared to fly an un-limited number of movements. All other types available at the time has strict limits on the number of movements allowed on any given day and equally strict noise abatement rules, which often imposed severe payload penalties, particularly on hot days.
