The word columbarium comes from the Latin word columba, meaning dove or pigeon. Traditionally, it refers to a resting place for the departed. Here, we borrow the term to honor the birds whose lives have been cut short by collisions. Each photograph is not just a record, but a memorial that remind us that casualties are not just numbers and statistics, but living beings whose presence once graced our skies. Photos displayed were taken by our volunteers at the SADM building, as well as other collision-prone locations around the campus.
