I've only read a few posts on this incident, but if this was not already stated, keep in mind that if you depart an airport that has only short runways and another airport is just a few minutes away with a much longer (suitable) runway, you might decide to go there instead. You would/should not be criticized for going to a nearby military base with a long runway in this situation. In the US, after you "declare an emergency" as a precaution, you can do whatever you need to (except in one part of Nevada...).
You can call for your "Engine Failure" or Eng Fire" procedures, and have these done, in about the same time as you would flying a fairly long downwind at the departure airport, while the Non-Flying Pilot goes through all 'clean-up' items, (and quickly briefs ATC and the cabin, then reviews the instr. procedure) prepares to land at the other nearby airport.
