The plane came by in a level flight, smoke pods were turned off. During this level flight I took a shot of it, and there were flames coming out of the smokepods, making it look like the "missiles" were about to be fired.
See what I mean? How is this caused? Is it a residue of the oil that creates a flame?

I don't know the answer , but I was wondering ......... if these smoke pods can be turned on and off several times during an airshow demonstration, then perhaps those small flames are used to re-ignite the oil/agent that creates the smoke. Just a thought.

The Smokewinders have ignition systems so no need for a pilot flame. A safe bet is that it is just gasoline still burning as they are turned off.
They operate by taking in ram air into a combustion chamber where an oil pump and a gasoline pump provides gasoline for combustion and oil for smoke generation. When the oil pump pressure drops, they turn themselves off but only after a brief delay. The picture is probably taken during this dealy, when the Smokewinders are burning only gasoline.

I thought I was doing good trying to avoid those airport hotels... and look at me now.
