Call me confused etc, I understood that the difference between an aircraft running 2B and 3I was basically that those running 3I had gone through a technical refresh, no added capability, just a different platform, like running Office 95 on Windows XP.
At one point this summer I read that 2B was much more stable than 3I, as is said, there must have been some upgrades. As a matter of interest what software version were the USAF aircraft that came over the pond? I personally thought it was brave to try a long flight with a 3I aircraft, when it had been published that they needed to reboot every X hours, it would not have been too helpful if one had ditched whilst rebooting west of Ireland, no let's not change to MRA4 discussions.
As I said a bit of clarity would be helpful, even if it is as basic as the software instabilities in 3Ix have been sorted out in 3Ix2, as proven by Y.....
