1. I was on a UA 737 from Reno to Den. On takeoff, we went thru a flock of geese and the right engine caught fire. The pilot killed the engine, dumped fuel and we did an emergency landing. Lots of screaming and praying as that engine made a huge grinding noise as the goose was (do I say it?) cooked.
2. Twice lost engines in flight (low oil pressure) but we just landed and switched planes.
3. Ord-Den on UA. At Denver Int'l during a snow storm, a truck got lost and wandered onto the runway. We aborted a landing which would've hit the truck.
