You're most likely to encounter a common aircraft type. Airline sompanies have reserve pilots that they can call on short notice, so it's highly unlikely that ATC will be unable to find someone to help. If you're in a small plane, there are many flying clubs they can call. All of this in the case that there are no pilots available on the current airport. See this video for an example of an SEP pilot landing a King Air: http://flash.aopa.org/asf/pilotstories/pinchhittingkingair/ http://flash.aopa.org/asf/pilotstories/pinchhittingkingair/
