WASHINGTON, Jan 30 (Reuters) - President Donald Trump

said on Thursday that air traffic control systems have not been

built properly, speaking in the wake of a deadly midair

collision between an American Airlines ( AAL ) regional passenger jet

and a U.S. Army Black Hawk helicopter near Washington D.C.

"They spent a lot of money renovating a system, spending

much more money than they would have spent if they bought a new

system for air traffic controllers, meaning the computerized

systems. There are certain companies that do a very good job.

They didn't use those companies," Trump said.
