It also left considerable radiation behind. (sound like an ice & rock comet ?)

After the event, the skies were lit up at night for days, hundreds of miles away.

At around 7:17 a.m. local time, Evenks natives and Russian settlers in the hills northwest of Lake Baikal observed a column of bluish light, nearly as bright as the Sun, moving across the sky.

Draw your own conclusions.

There is no reason to really dig into the Tunguska event, there is nothing we can learn from it by creating new Hypothesis. There is a lot of evidence supporting the current theory, large explosions in the air can cause the pattern seen, asteroids/comets can explode before hitting the ground if the conditions are right. Finally there is physical evidence backing it up as well. There will not be a better explanation unless a similar event happens again allowing new evidence to be brought forth.

I'm not worried about Toutatis - it's Apophis that is going to give us cause for concern soon enough.

Why is it a cause for concern? It's 17 years from now for starters (well, 16 since it's the end of 2012 I suppose), it won't come anywhere near close enough to hit the planet in 2029, and even if our gravity affects it's orbit, the chance of it going through the keyhole at just the right degree is extremely small. And even then, if it did do that, it's another 7 years after that before anything happens. We have 24 years to plan for Apophis and it's extremely unlikely rendezvous with Earth.

Well, I guess we survived another near miss. Can't wait til next time.
