Minimum safe altitude warning (MSAW) is an automated warning system for air traffic controllers (ATCO). It is a ground-based safety net intended to warn the controller about increased risk of controlled flight into terrain accidents by generating, in a timely manner, an alert of aircraft proximity to terrain or obstacles.
A local restaurant owner heard "loud bangs" that sounded like the backfiring of a motorcycle engine, leading him to rush to the restaurant rooftop and record a 54-second video on his cell phone of the aircraft's descent and crash which subsequently went viral.

Non-discrete mode A code reserved use in mode S radar/ADS-B environment where the aircraft identification will be used to correlate the flight plan instead of the mode A code. [1] US: Used exclusively by ADS-B aircraft to inhibit mode 3A transmission. [3] US: Non-discrete code assignments in accordance with FAA Order JO 7110.65, 5-2.
A voice warning system is a system designed to alert the crew of an aircraft to imminent safety hazards. It is often known as a Bitchin' Betty, a slang term used by some pilots and aircrew and submariners (mainly North American). The enunciating voice, in at least some aircraft systems, may be either male or female.

The civilian aircraft frequency for voice distress alerting is 121.5 MHz. Military aircraft use 243 MHz (which is a harmonic of 121.5 MHz, and therefore civilian beacons transmit on this frequency as well). Aircraft can also signal an emergency by setting one of several special transponder codes, such as 7700.
NTSB investigators reported discovering critical controls on some Boeing 737s — including its MAX airplanes — could jam after discovering a part that could fail.
A discrete transponder code (often called a squawk code) is assigned by air traffic controllers to identify an aircraft uniquely in a flight information region (FIR). This allows easy identification of aircraft on radar. [6] [7] Codes are made of four octal digits; the dials on a transponder read from zero to seven, inclusive. Four octal digits ...
