AR, the BAE delivery pilot, was in the RH seat training the local pilot. To cut a long story short, they were flying in airspace that they shouldn't have been in hence the Angolan Mig pilot had a pop at them.
The aircraft at the time only had approx 80 hours on it. The aircraft wing was split put in a AN124 transporter and flown back to Manchester and road shipped to Hawarden for repair (repair took approx 1 year). A perfect advertisement for the rugged design of the HS125.
