To find one of your own Aeros, you can look on the My Dashboard screen, the My Schedule screen, or the My Aeros screen. Keep in mind that those screens only list current, open Aeros. If you're looking for an Aero that you have completed, you can look on the My Timesheet screen or on the My Schedule screen (completed Aeros are in black ink), or on certain Quick Filter views on My Dashboard.
To find an Aero for anyone in the firm, you can look on the Manage > Aeros screen or the Scheduled Aeros report (you might have to customize it to get the date you want). If you're looking for a completed Aero, you can look on the Manage > Time screen, some Quick Filter Views on the Manage Aeros screen, or the Completed Aeros report.
