A directive Trump issued Wednesday expands testing for flights over people, nighttime operations and at far greater distances and with packages. The program encourages states and local governments to seek approval from the Federal Aviation Administration for speedy testing and expanded use.

Amazon, Alphabet and others are developing drone delivery technology, in hopes of bringing shipments faster and cheaper to customers. However, these companies still need to answer tough questions about the drones’ safety and effectiveness before they can reach the public.

The move comes as the drone industry experiences meteoric growth. The FAA expects the number of commercial drones to grow from 42,000 at the end of 2016 to about 442,000 aircraft by 2021.

New FAA regulations for commercial use of drones went into effect in August 2016, making it easier for pilots to use drones for everything from structural or crop inspection to search-and-rescue operations to film production. But certain regulations, including flying over people, remained in place.

Safety and security concerns have prompted the FAA to prohibit flights of unmanned aerial vehicles near US monuments, including the Statue of Liberty, Mount Rushmore and a handful of other Interior Department sites. The FAA said it took the action at the request of the US national security and law enforcement agencies.

Earlier this month, the FAA granted a waiver allowing CNN to make routine drone flights above crowds — the first time the federal agency awarded a waiver for unlimited flights of unmanned aerial vehicles over people.

The memo said that the Transportation Department would coordinate with the Defense Department, Homeland Security and Justice Department to mitigate public safety and national security risks in selecting proposals.

The government worries Kaspersky Lab has ties to the Russian government.

The allegations, which have cropped up over the last several months, range from Kaspersky working with the Russian government to Kremlin spies hacking the antivirus software and using it without the company knowing.

A Bloomberg article in July said internal emails showed Kaspersky Lab was working closely with Russia’s FSB, the country’s equivalent to the FBI. This came a month after FBI agents visited Kaspersky employees in the US, questioning the company’s motives.

“The case against Kaspersky Lab is overwhelming,” Sen. Jeanne Shaheen, a Democrat from New Hampshire, said in a statement. “The strong ties between Kaspersky Lab and the Kremlin are alarming and well-documented.”
