UAL1003 had just departed KSFO from runway 1R on March 23 when the flight crew reported possibly hitting a drone just after becoming airborne. The aircraft climbed to 5000 feet and was given vectors while they tried to figure out what exactly had happened. The crew decided to return to KSFO and declared an emergency as a precaution. They landed safely a short time later on runway 28R. Adding to this incident was some wildlife crossing a runway that forced the tower controller to cancel a takeoff clearance.
