Mach Number

Since it is possible to hold the mouse over the airspeed on the flight status page and see the mach number, would it be possible to have the same feature available on the enroute page, the page where the near to the minute position, speed and altitude data is?

BTW Just a general question, I was looking at JBU512 tonight, and on the en route page, it showed data being received until 11:39, but the main page said the plane landed at 11:31. Which is the correct time?

It looks like the flight was marked as arrived while it was still in the air; could have been an accident when it was handed over to tower. From the tracklog it looks like the arrival was actually at about 11:40.

Thanks for the quick reply.
