Using something specific in the present-moment scene to create a direct connection with a particular aspect of the flashback memory (general, specific, or anchor) will help you segue smoothly into the flashback scene.
The article will likely highlight the use of sensory details to evoke a memory and initiate the flashback. This could be a sight, smell, sound, taste, or touch that is strongly associated with the past event.
Flashback is currently supported only over DML statements (INSERT, DELETE, UPDATE). An upcoming version of MariaDB will add support for flashback over DDL statements (DROP, TRUNCATE, ALTER, etc.) by copying or moving the current table to a reserved and hidden database, and then copying or moving back when using flashback. See MDEV-10571.
The real work of Flashback is done by mariadb-binlog with --flashback. This causes events to be translated: INSERT to DELETE, DELETE to INSERT, and for UPDATEs, the before and after images are swapped.
Model 88-5 FBR (R&L) regulator-type FlashGuard flashback arrestor prevents the reverse flow of gases with built-in check valves. It extinguishes flashback fire with a stainless steel sintered element. The 100 micron inlet filter helps keep dust and dirt out. Due to flow capacity, this model should not be used with tip sizes larger than No. 5 hand cutting tips (except No. 4-NFF), No. 5-1/2 machine cutting tips, No. 4 acetylene heating tips, No. 2 alternate fuel heating tips and No. 2 RBP cleaning head (no limitation with RBA). This model features 9/16 in. -18 CGA B-size connections. It is for use with oxygen and fuel gas.
Remember, most fiction is a balance of action and exposition in writing. When you use flashback, you are taking us out of the present moment to introduce information. Pacing stops. Action stops. You have to keep that very much in mind and, first and foremost, keep flashbacks short. (Additional tips on writing backstory here.)
This is a great topic because flashbacks can be helpful but tedious to work with. I have had trouble with flashbacks before. For one of my writing projects, I wanted to start off with a small flashback for a prolouge however, with my original draft, it would not have worked because the first chapter was a flashback, as well. I did not want to start off my novel with two flashbacks because I thought it would be too confusing for the reader. So in the end, I decided to use just one flashback and rewrite a different first chapter. I do realize you have written that you should stay away from beginning a story with a flashback and you did bring up a good point about doing so. Maybe I will go back and see what I can do with my story. Thanks for the advice and ideas.

Oracle Flashback Technology is a group of Oracle Database features that let you view past states of database objects or to return database objects to a previous state without using point-in-time media recovery.
Oracle Flashback features use the Automatic Undo Management (AUM) system to obtain metadata and historical data for transactions. They rely on undo data, which are records of the effects of individual transactions. For example, if a user runs an UPDATE statement to change a salary from 1000 to 1100, then Oracle Database stores the value 1000 in the undo data.
Undo data is persistent and survives a database shutdown. It is retained for the time specified by undo_retention, or up to the tuned undo retention in the presence of Automatic Undo Management (AUM). By using flashback features, you can use undo data to query past data or recover from logical damage. Besides using it in flashback features, Oracle Database uses undo data to perform these actions:
After executing a CREATE TABLE statement, wait at least 15 seconds to commit any transactions, to ensure that Oracle Flashback features (especially Oracle Flashback Version Query) reflect those transactions.
In application development, you can use these flashback features to report historical data or undo erroneous changes. (You can also use these features interactively as a database user or administrator.)
Use this feature to retrieve metadata and historical data for a specific time interval (for example, to view all the rows of a table that ever existed during a given time interval). Metadata for each row version includes start and end time, type of change operation, and identity of the transaction that created the row version. To create an Oracle Flashback Version Query, use the VERSIONS BETWEEN clause of the SELECT statement.
Use this feature to retrieve metadata and historical data for a given transaction or for all transactions in a given time interval. To perform an Oracle Flashback Transaction Query, select from the static data dictionary view FLASHBACK_TRANSACTION_QUERY.
Use this feature to set the internal Oracle Database clock to an earlier time so that you can examine data that was current at that time, or to roll back a transaction and its dependent transactions while the database remains online.
Use Flashback Transaction to roll back a transaction and its dependent transactions while the database remains online. This recovery operation uses undo data to create and run the corresponding compensating transactions that return the affected data to its original state. (Flashback Transaction is part of DBMS_FLASHBACK package).
Use Flashback Time Travel to automatically track and archive historical versions of changes to tables enabled for flashback archive, ensuring SQL-level access to the versions of database objects without getting a snapshot-too-old error.
For an automatically extensible undo tablespace, Oracle Database retains undo data longer than the longest query duration and the low threshold of undo retention specified by the UNDO_RETENTION parameter.
Setting UNDO_RETENTION does not guarantee that unexpired undo data is not discarded. If the system needs more space, Oracle Database can overwrite unexpired undo with more recently generated undo data.
To allow a specific user to enable Flashback Time Travel on tables, using a specific Flashback Archive, grant the FLASHBACK ARCHIVE object privilege on that Flashback Archive to that user. To grant the FLASHBACK ARCHIVE object privilege, you must either be logged on as SYSDBA or have FLASHBACK ARCHIVE ADMINISTER system privilege.
To use Oracle Flashback Query, use a SELECT statement with an AS OF clause. Oracle Flashback Query retrieves data as it existed at an earlier time. The query explicitly references a past time through a time stamp or System Change Number (SCN). It returns committed data that was current at that point in time.
For example, you can find employees with valid employee information as of a particular timestamp or between a specified start and end time in the specified valid time period. (For more information, see Temporal Validity Support.)
Suppose that you discover at 12:30 PM that the row for employee Chung was deleted from the employees table, and you know that at 9:30AM the data for Chung was correctly stored in the database. You can use Oracle Flashback Query to examine the contents of the table at 9:30 AM to find out what data was lost. If appropriate, you can restore the lost data.
You can use the AS OF clause in queries to perform data definition language (DDL) operations (such as creating and truncating tables) or data manipulation language (DML) statements (such as INSERT and DELETE) in the same session as Oracle Flashback Query.
You can store the results by preceding Oracle Flashback Query with a CREATE TABLE AS SELECT or INSERT INTO TABLE SELECT statement. For example, this query reinserts into table employees the rows that existed an hour ago:
Oracle Flashback Version Query returns a table with a row for each version of the row that existed at any time during the specified time interval. Each row in the table includes pseudocolumns of metadata about the row version, which can reveal when and how a particular change (perhaps erroneous) occurred to your database.
Table 19-1 describes the pseudocolumns of metadata about the row version. The VERSIONS_* pseudocolumns have values only for transaction-time Flashback Version Queries (that is, queries with the clause BETWEEN TIMESTAMP start AND end).
Starting System Change Number (SCN) or TIMESTAMP when the row version was created. This pseudocolumn identifies the time when the data first had the values reflected in the row version. Use this pseudocolumn to identify the past target time for Oracle Flashback Table or Oracle Flashback Query.
Operation performed by the transaction: I for insertion, D for deletion, or U for update. The version is that of the row that was inserted, deleted, or updated; that is, the row after an INSERT operation, the row before a DELETE operation, or the row affected by an UPDATE operation.
For user updates of an index key, Oracle Flashback Version Query might treat an UPDATE operation as two operations, DELETE plus INSERT, represented as two version rows with a D followed by an I VERSIONS_OPERATION.
Use Oracle Flashback Transaction Query to retrieve metadata and historical data for a given transaction or for all transactions in a given time interval. Oracle Flashback Transaction Query queries the static data dictionary view FLASHBACK_TRANSACTION_QUERY, whose columns are described in Oracle Database Reference.
