Many of the world's billionaires will be at the World Economic Forum in Davos, which kicks off Tuesday, and private jet provider Air Charter Service predicts there will be close to 1,500 private jet flights over the week.

By the numbers: That's a 50% increase from the service's 2018 prediction of 1,000 private jet flights. The website noted it ended up totaling more than 1,300 aircraft movements, an 11% increase from 2017 and the highest number on record.

  • Air Charter Service's website also points out: "According to WingX figures the average number of aircraft movements — arrivals and departures ... for the week of the forum ... rises to an average of 218 — an increase of 335%, with the two busiest days ... seeing 251 and 301 movements, respectively."
  • "Top countries involved in terms of arrivals in and departures out of the airports were Germany, France and the U.K. The U.S. came in fourth with 41 arrivals and 51 departures."

Yes, but: The estimates do not include helicopter trips.

Louisville officer: "Breonna Taylor would be alive" if we had served no-knock warrant

Sgt. Jonathan Mattingly, the Louisville officer who led the botched police raid that caused the death of Breonna Taylor, said the No. 1 thing he wishes he had done differently is either served a "no-knock" warrant or given five to 10 seconds before entering the apartment: "Breonna Taylor would be alive, 100 percent."

Driving the news: Mattingly, who spoke to ABC News and Louisville's Courier Journal for his public interview, was shot in the leg in the initial moments of the March 13 raid. Mattingly did not face any charges after Kentucky Attorney General Daniel Cameron said he and another officer were "justified" in returning fire to protect themselves against Taylor's boyfriend.

U.S. vs. Google — the siege begins

The Justice Department fired the starter pistol on what's likely to be a years-long legal siege of Big Tech by the U.S. government when it filed a major antitrust suit Tuesday against Google.

The big picture: Once a generation, it seems, federal regulators decide to take on a dominant tech company. Two decades ago, Microsoft was the target; two decades before that, IBM.

Why the stimulus delay isn't a crisis (yet)

If the impasse between House Speaker Nancy Pelosi and the White House on a new stimulus deal is supposed to be a crisis, you wouldn't know it from the stock market, where prices continue to rise.

  • That's been in no small part because U.S. economic data has held up remarkably well in recent months thanks to the $2 trillion CARES Act and Americans' unusual ability to save during the crisis.
