 Airflow UI
 ^^^^^^^^^^
 
+Why did my task fail with no logs in the UI?
+--------------------------------------------
+
+Logs are [typically served when a task reaches a terminal state](https://airflow.apache.org/docs/apache-airflow/stable/administration-and-deployment/logging-monitoring/logging-tasks.html#serving-logs-from-workers). Sometimes, a task's normal lifecycle is disrupted, and the task's
+worker is unable to write the task's logs. This typically happens for one of two reasons:
+
+1. [Zombie Tasks](https://airflow.apache.org/docs/apache-airflow/stable/core-concepts/tasks.html#zombie-undead-tasks)
+2. Tasks failed after getting stuck in queued (Airflow 2.6.0+)

Review Comment:
   What the Airflow 2.6.0+ means?
   if task is stuck in queue it means it didn't reach worker. "extracting" it from the queue can be done with any Airflow version.
