Souix city.
SR had number 2 go bang out of West Africa which took out two of the three systems before Souix city with one of the big chiefs flying it who was very competent. They were very lucky as the fan blade missed the third system but did take out the apu fuel line.

Douglas were negligent in not having a slat locking system like wot uvva kites I drove.
