Or maybe if these "three yellow buckets" are really
the "tree spot lights directed at the aircraft" mentioned
by the Polish 36th squad pilots and other Russian pilots,
as the only approach lights,
then this might be THE ANSWER: WHY ??
The pilots mentioned above all confirmed the these lights were
expected (supposed) to be "at the threshold".
but from the same blog and image below they were in zone 5.
This zone 5 is at least 800m before the runway threshold.
If the pilots took them for the runway lights, then
this is
the answer, why they were so low.
If this would have really been the runway, than their glide-path
would have been perfect...
(do you remember the gear touch down marks almost exactly at this point?)
