before landing check list:
have DC8 and 9 time and I know about V1 procedures and echo just about what everyone here has said. However let's visit the AF Concord situation. IF the fire developed after V1 and IF the crew new about the situation do you think the captain would have continued THAT takeoff and if not do you think the outcome would have been not as bad? What would you have done? Food for though eh?
Many years ago an Old Continental 707 had an engine on the left side (I think #2, have an uncontained engine failure at LAX. They had just rotated. Debris from # 2 bounced off the runway and took out engine #3. It was hairy but they were able to climb out and return for landing.
Then again it was a fan-powered 707.
