WASHINGTON, April 2 (Reuters) - Senate Commerce

Committee chair Ted Cruz said Wednesday the panel plans to

subpoena the U.S. Army to force the military to turn over a 2024

report detailing why the Army routinely failed to use a safety

system known as ADS-B on helicopter flights around Reagan

Washington National Airport.

An Army Black Hawk helicopter did not have ADS-B operating

during a routine training mission when it collided with an

American Airlines ( AAL ) regional jet on January 29, killing 67

people. The Army last week refused senators' request for the

memo.
