A courier truck carrying an emergency aviation signalling device called an ELT emitted an emergency signal as it was traveling through downtown Regina Saskatchewan. The battery had not been removed from the device and it was activated.
Federal Aviation officials reported that the ELT began to emit a signal shortly after 7 AM CST on Thursday. The signal immediately triggered an emergency response by crews in Winnipeg Manitoba.
Officials said:"An extensive communication search failed to locate the signal," Officials thought a plane must have crashed. Search and rescue planes were sent to investigate both from Regina and Winnipeg.
The teams were able to trace the signal to downtown Regina. But of course there was no crash there. Officials noted:"The signal was homed to an incoming express post truck with a live, armed ELT inside," "The shipper was contacted and it was found to belong to an amateur-built aircraft."
Apparently the owner of the device had shipped the ELT by expresss but had not removed the battery. For more see this article.
