"The helicopter had vision of the plane," Trump added, but "for some reason there weren't adjustments made," and lamenting, "for some reason, it just kept going."
"But one thing we do know, there was a lot of vision, and people should have been able to see that. At what point do you say, well, that plane's getting a little bit close."
Trump also blasted the Biden administration for air traffic control systems having not been built properly.
"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," Trump said. "There are certain companies that do a very good job. They didn't use those companies."
