Arrgh, TyroPiccard, keep it simple, please! Read all my posts.
If you are in the air, and your TL is stuck, you go around.
If you are on the ground, you brake on one engine already, and your other TL is stuck, you don't go around, you cut the engine.
Of course I don't know what happened, I'm no wizzard. I just say what the most plausible answer is. You can find here thousands of theories. According to Ockham's knife (read this theory!), mostly the most simple theory is the correct one.
