5 things to know for your new day -- Tuesday, November 3

(CNN)Metrojet crash probe continues. Ben Carson leads another poll. And it's a tough day for knights and dames.

It's Tuesday, and here are five things to know for your new day.

PLANE CRASH

    Questions: Technical faults? Human error? Terrorism? The questions are swirling as authorities try to find out what caused Metrojet Flight 9268 to tumble from the sky. Experts think technical failure is the must likely reason, so they're taking no stock in claims by Islamic militants that they brought the Russian jetliner down. A heat flash was detected at the time of the crash, so that data is being analyzed to see if it has anything to do with the disaster.

    BILL COSBY

    More questions: Looks like Bill Cosby will be deposed again. A court granted a motion yesterday allowing for Cosby and his ex-attorney to be questioned as part of model Janice Dickinson's defamation lawsuit against the comedian. The court ordered the deposition take place by November 25. In a separate case, Cosby was deposed last month in Boston about his alleged serial doping and groping of young women.

    AUSTRALIA

    Title twist: No more knights and dames in Australia. Prime Minister Malcolm Turnbull says the titles are inappropriate for Australia's modern honor system, and Queen Elizabeth has agreed to end the practice. But if you are already a knight or dame in Australia, don't worry. The change won't affect those already blessed with the titles.
