I wish Saintsman would give us a bit more detail about this, it's new to me.
I'd assumed that there were REAL problems beyond merely validating software, but I'm beginning to wonder. Could this be a case of the aircraft being grounded more by red tape and over-caution than by real technical problems?
I'm a HUGE fan of Boscombe, but I remember the fuss surrounding Typhoon's clearance - where there were risks, but these were deemed acceptable by the user. One wonders whether the Mull of Kintyre crash hasn't led to much more risk aversion where the platform is a Chinook?
