Transit Police have some explaining to do.
The Canadian Taxpayers Federation revealed Transit Police accidentally left an explosive device on a plane, and didn't know it was missing for two days.
It happened in 2011 after a dog training exercise.
BC director for the CTF, Jordan Bateman, says this was an expensive mistake.
"They had to involve Richmond and airport RCMP, YVR security, Transport Canada involved, you're talking about tens of thousands of dollars at least in fast time into this file."
The incident was revealed through a Freedom of Information request.
