Two miles per second is 120 miles a minute or 7200 miles per hour. Considering the speed of sound at sea level on a standard day (temperature dependent and more complicated to calculate than I can explain) around 761 mile per hour, the T1 was going over 9 times the speed of sound. I don't think the T1 could go that fast.

One hell of a sonic boom I bet. The doppler effect on the whistle would be awesome!
