Actually, the ions can have lifetimes upwards of 10mS, dependent on the
condition of the surrounding air. The Tesla Coil happily takes full advantage
of this, as can be seen by watching videos of the streamer propagation
in slow motion. Some good empirical data on ion lifetimes in standard air
can be found on pp359-360 of 'Gaseous Conductors' by Cobine.
