One of the coolest fly by I have seen.

Smokewinders! Have to click to watch

Wingtip flares in the vortices!  So cool it looks faked!

Cool, At exactly the right temperature/humidity/wind the smoke will linger for a minute or so, combine that with a vortex to contain it and you get that stunning result.

Eric and I got a barrel of smoke oil!  The smoke systems in both
S-2B's are working really well, and when we did a formation takeoff
yesterday, I told the Tower we were going to run smoke.

So I stop on the runway, look over, check Eric's canopy, get
the head nod from him, look forward and right vertical finger
twirl for throttle, with the brakes on.

Then I put the smoke on.  See, instead of hand signals, when
I turn the smoke on, Eric turns the smoke on, and when I turn
the smoke off, Eric turns the smoke off.  We use smoke signals
instead of hand signals.  It's pretty complicated, but he gets it.

So I sit there with both of us at 2,000 RPM and both of us
pumping out smoke on the runway.  It was glorious.  After a
few seconds, I nod my head forward for brake release and
up to 24 inches I go.

Victory was mine, when Tower told the aircraft landing behind
us to overshoot because of all the smoke on the runway  ^-^

If I could get the AWOS to issue a SPECI with zero vis for
the airport, I think I could probably retire a happy man.

You guys in Canada give hugs and kisses to David Suzuki
next time you see him, ok?  Tell him I miss him.

I have some amazing footage of an aircraft doing low passes
(I have to wait a number of years before I can release it) and
the weird thing is that you could hear a weird crackle as he
flew by.

I think it was static electricity from his powerful wingtip vortices -
he was pulling lots of G.  As Peter says, you need the right
conditions.
