Yet Another Tornado [or two]

I usually hate it when anyone accuses me of taking a 'lucky' shot. After
getting up before dawn to drive a hundred miles to climb a few hundred
feet up the side of a hillside that you found by staking out quite a few
others that were useless, then waiting all day [in the cold wind] to
shoot sometimes only one pass of a plane [and often nothing] luck is not
a word I allow.
But to get two Tornados together here was very fortunate as I was
panning the one in the foreground with the camera on continuous shooting
as the other flew through the viewfinder behind it.
I'll take 'lucky' for this one.
