but then again: why would one tell an aircraft to go-around when it's landing on a perfectly suitable (to the point of being used as a runway up to 4 days before), obstacle-free strip?
The key point here is it was a TAXIWAY used as a RUNWAY FOUR DAYS BEFORE.The runways where I am are inspected regularly for detritus damage and general bits and pieces. I would not let you land on the duty runway without regular inspections, I am sure as a sure thing I am NOT going to let you land on a taxiway.
I don't know who issued landing clearance but Approach (in my airport) has a remote clearance to land system. It is rarely used but is available.
The only form of non radio equipment we have is an ALDIS LAMP set to RED.
