"Downtown Las Vegas Area" is the name assigned by the Nevada Gaming Control Board NGCB which includes the Downtown Las Vegas area casinos and the Stratosphere Tower which is located 2 mi from Fremont Street.
 The city of Las Vegas uses the term Downtown Gaming for the casinos near the Fremont Street Experience.

Bonanza Air Lines was an airline (known at the time as a "local service" air carrier as defined by the federal Civil Aeronautics Board) with routes in the Western United States (and eventually Mexico) from 1945 until it was merged with two other local service air carriers to form Air West in 1968.
 Its headquarters was initially located in Las Vegas, Nevada and was later moved to Phoenix, Arizona in 1966.
Korean Air Lines Flight 007 (also known as KAL007 and KE007) was a scheduled Korean Air Lines flight from New York City to Seoul via Anchorage, Alaska.
 On September 1, 1983, the South Korean airliner serving the flight was shot down by a Soviet Su-15 interceptor.
 The Boeing 747 airliner was en route from Anchorage to Seoul, but deviated from its original planned route and flew through Soviet prohibited airspace around the time of a U.S. aerial reconnaissance mission.
 The Soviet Air Force treated the unidentified aircraft as an intruding U.S. spy plane, and proceeded to destroy it with air-to-air missiles, after firing warning shots which were likely not seen by the KAL pilots.
 The Korean airliner eventually crashed in the sea near Moneron Island west of Sakhalin in the Sea of Japan.
 All 269 passengers and crew aboard were killed, including Larry McDonald, a Representative from Georgia in the United States House of Representatives.
 The Soviets found the wreckage under the sea on September 15, and found the flight recorders in October, but this information was kept secret until 1993.

Delta Air Lines Flight 191 was a regularly scheduled Delta Air Lines domestic service from Fort Lauderdale, Florida, to Los Angeles, via Dallas that crashed on August 2, 1985, at 18:05 ().
 The Lockheed L-1011 TriStar operating this flight encountered a microburst while on approach to land on runway 17L (now marked 17C) at Dallas/Fort Worth International Airport (DFW).
 The pilots were unable to escape the weather event and the aircraft struck the ground over a mile short of the runway.
 The flight hit a car driving north of the airport and two water tanks, disintegrating.
 The crash killed 136 people on board, including 128 of the 152 passengers and 8 of the 11 crew, and the driver of the car.
 The National Transportation Safety Board (NTSB) determined that the crash resulted from the flight crew's decision to fly through a thunderstorm, the lack of procedures and training to avoid or escape microbursts, and the lack of hazard information on wind shear.
