Southwest Flight 1380
Southwest Airlines flight WN1380 was operating from New York’s La Guardia Airport (LGA/KLGA) to Dallas’ Love Field (DAL/KDAL) when it experienced an uncontained engine failure to the number 1 (left) engine. The flight diverted to Philadelphia International Airport.
The flight departed New York at 14:43 UTC (10:43 EDT) and climbed through FL320 (32,000 ft) when the number 1 engine experienced a failure about 20 minutes after departure—shedding debris, including at least one piece that pierced the aircraft fuselage.
The flight crew initiated an emergency descent and requested vectors from air traffic control for the nearest airport, selecting to land and Philadelphia International Airport at 15:20 UTC (11:20 EDT).
The aircraft operating flight 1380 was N772SW (MSN 27880 L/N 601), a Boeing 737-700 powered by two CFM56-7B engines. The aircraft was delivered to Southwest Airlines in July 2000.
Flightradar24 data for Southwest 1380
Flightradar24 data for this flight includes Mode S data received from the aircraft and Multilateration (MLAT) data calculated based on Mode S data. This aircraft is not equipped with an ADS-B transponder. From the Mode S transponder we receive the flight’s call sign and reported altitude. Position and speed are calculated based on Multilateration. Vertical speed is calculated via the time difference of reported altitude values.
The following shows the aircraft’s altitude positions (in feet), ground speed (in knots) and vertical speed (in feet per minute) based on more granular data retrieved from the Flightradar24 network after the flight.
The maximum altitude received from the aircraft was 32,550 ft. Maximum calculated vertical speed was -7680 fpm.
The basic and granular csv files differ in time frequency of position reports. The granular data includes much more frequent position reports retrieved from the Flightradar24 network after the flight.
