A jet with 60 passengers and four crew members aboard collided Wednesday with an Army helicopter while landing at Ronald Reagan National Airport near Washington, prompting a large search-and-rescue operation in the nearby Potomac River. There was no immediate word on casualties or the cause of the collision, but all takeoffs and landings from the airport near Washington were halted as helicopters from law enforcement agencies across the region flew over the scene in search of survivors. Inflatable rescue boats were launched into the Potomac River from a point near the airport along the George Washington Parkway, just north of the airport. President Donald Trump said he had been “fully briefed on this terrible accident" and, referring to the passengers, added, “May God Bless their souls.” MORE: https://www.wtsp.com/article/news/nation-world/aircraft-down-washington-dc-potomac-river/507-415bed11-7043-4fa0-ab80-e24084f60665
