Display flight number, origin, destination, fl_orig_time as --"Departure Time", fl_dest_time as "Arrival Time". Format times in
NARA [144]

Answer:

Select "flight number", origin, destination, format(fl_orig_time, 'HH:mm' ) as "Departure Time", format(fl_dest_time, 'HH:mm') as "Arrival Time" from table_name order by flight_number

Explanation:

The script is used to select records from the table named 'table_name' and formatted to 24hr time format with the hour in capital letters (signifying 24 hrs). Then the inverted comma used for flight number is due to the space character ebtween the two words. In a select statement, order by comes after the table name. While as is used as an alias for a column in a table.
