The other forum say the "shassi" the wheels? are standardly let out, even before the Far Beacon, as part of the procedure.
So it can be both - the Polish president's plane was seriously minded to land OR it was "proving" to the bosses on board that they are seriously minded to have a look around and attempt to do it. Because what if will see the runway.
They think in either case the kommander would let those wheels out.
