To add to the chaos in Nigeria yesterday, a B727 skidded off the end of R/W18L at Lagos in the early afternoon. It would appear that no-one was hurt, but no idea as to the state of the a/c, which was at rightangles to the r/w, and around 200m off the end. The airfield was subsequently closed for around 4 hours. When I went in and out yesterday evening, the disabled a/c was causing problems in that all arrivals had to be on 18L (ILS) due weather, but departures off 36R.
