I have been using FlightRadar for some time, both on my PC and my phone, but had never noticed the Cockpit view button. I can see that I will be watching these a number of times for the airports I visit in the USA and UK.
The website for those who haven't explored this is http://www.flightradar24.com/. Once the flights have uploaded, click an aircraft of interest and then choose the cockpit view in the window which slides out from the left.
You may need to update the Google Earth plugin if it doesn't work. I also had to temporarily disable my firewall to allow Flightradar24 to download and install the plugin.
