Picking the bones out of the original thread the basic question was, should this aircraft turn finals? and in my opinion (and it appears to be the general opinion), yes. Next question what should one do from that point on due to a lack of landing clearance. Well rule 5, low flying rule is relaxed for any aircraft which lands and takes off in accordance with normal flying practice at a licenced aerodrome. So what at what height do you go around? answer...a safe height..or alternatively, how long's a piece of string(imho).
I wonder if the same situation would have occured if the aircraft was say a 737 full of slf ?
