There is about 3-4ft of wing missing an inch further along and he would have lost the port aileron. Pilot vacated and said it was a bird strike, then changed the story about 4 times, I guess the reason they carried on was the money involved, later on that evening a HS125 from Biggin came in to take them down to Lisbon. Yet another case of stupidity vs. money, there is almost no way they didn't notice what had happened, any sensible pilot would have diverted to nearest field.
