Subject: St. Petersburg to Moscow

I wonder if any Ziners have done the trip from St Petersburg to Moscow.

Having found it difficult to find information on the net (probably due to the fact that I don't speak Russian) I thought it best to ask here.

What is the best way to do this journey (by train or plane)? What are the pros and cons of each way, especially given Aeroflot's "safety" record?
