Flares light up Summerside Harbour on Wednesday, Dec. 16, 2015 during a coast guard and military training exercise.
A training exercise in the waters off Summerside Wednesday evening created confusion and worry among some residents in the area.
RCMP issued an advisory last evening informing the public that the bright lights they were seeing in the sky were the result of a training exercise being conducted off of Summerside between the coast guard and the military.
Illuminated flares were being dropped from aircraft as part of the exercise which ended just before at 9 p.m.
The commontion drew many curious residents to the shoreline, some of whom were alarmed by what they were seeing.
In an email to TC Media one commentor said they were shocked when they saw the lights.
"I was worried that it might be something serious and as someone who was listening to the radio and driving, seeing these lights was surprising."
