Beeline I presume that is as a result of BA56 out of Johannesburg. I understand the mod only applies to Rolls-Royce engines. I must admit I admire the BA crew on that one, great job and proves yet again the value of good old fashioned hand skills.
For those not familiar with the incident, during take-off a false reverse thrust signal retracted the leading edge sections during take-off. Around 160 knots if my memory is correct, very exciting when hot, high and heavy.
