One of my more memorable moments working San Francisco Tower a few years back;
To set the scene, we were in normal operations which had aircraft arriving 28's and departing 1's. The 28's come in along the bay shoreline to the airport where the departure end of runway 1L/R is the water(bay).
ME: SWA704, San Francisco Tower, Traffic departing the northbound on the crossing runway prior to your arrival, a Airbus A320, Wind 280 at 5, Runway 28R, Cleared to land.
SWA704: Roger Cleared to land 28R and Will be looking for the Airbus
ME: UAL1598, San Franisco Tower, Wind 280 at 5, Runway 1R, Cleared for Takeoff.
UAL1598: Rolling 1R
<approx 1 min passes>
SWA704: Tower, SWA704 has an aircraft in sight but it appears to be a sea plane, still negative visual on the airbus.
<10 seconds of silence>
(Obvisouly was the UAL): Yeah Yeah Yeah, Its us in the bay, apparently we took our Airbus sim to a whole new level by simulating the fly-by-wire controls however we forgot to plugin our fly-by-wire joystick to the computer.
SWA704: Tower, SWA704 would like make this a low approach fly by to honor the pilot in the Scarebus....We are proud to always be going in our boeing.
