Personally I would descend to the MEA and start heading towards any airfield in the general direction of a larger one, if it becomes confirmed and uncontrolled I would either land at the small airfield and go off the end or ditch if becoming unmanageable. A crash in control is better than one out of control even if both have a pretty certain outcome. If there is no sign of fire by the time we are close to the small airfield I would opt to continue and land at the larger one that is further.
