declined to comment on the situation.During Wednesday’s hearing, Cruz threatened the Army with a subpoena if it did not give the committee a copy of its memo spelling out when its aircraft are allowed to fly without a key system that broadcasts their location to other aircraft turned on.

The fact that system wasn’t activated in the Black Hawk that collided with the passenger jet is a key concern investigators have highlighted. With the location system turned off, the tower had to rely on radar for updates on the helicopter’s position that only came once every four seconds instead of every second before the crash.“It begs the question, what doesn’t the Army want Congress or the American people to know about why it was flying partially blind to the other aircraft and to the air traffic controllers near DCA (Reagan airport)?,” Cruz said. “This is not acceptable.”The Army didn’t immediately respond to an inquiry Wednesday about the memo. The U.S. Army’s head of aviation, Brig. Gen. Matthew Braman, told the Senate Commerce Committee last week that he wasn’t sure if he could provide the memo because it is part of the investigation, but the head of the NTSB assured him that would be okay.

Piloted by Michael Groff, the plane had left the Boston suburbs early Saturday morning, picking up Karenna Groff and Santoro in White Plains before making the short trip to the Catskills to celebrate Karenna Goff’s 25th birthday.But at about 11:57 a.m., Michael Groff informed air traffic control that he’d missed the initial approach to the runway at Columbia County Airport, according to the report. The controller then gave him new instructions for the landing, which Groff acknowledged a little after 12 p.m.

About a minute later, though, the controller warned Groff the plane was flying at a low altitude, the report states. The pilot never responded, and, despite multiple warnings, air traffic control received no further radio transmissions from the plane until radar contact was eventually lost.The Mitsubishi MU-2B-40 crashed in snow covered terrain roughly 10 miles (16 kilometers) south of the airport.
