The 134 can indeed apparently be a bit of a challenge on landing and there have been a number of accidents at this stage. It seems to have performance charactersitics which can lead to it getting away from the crew occasionally, notably when in combination with other difficulties.
It is common on Soviet types for the crew to include at least one supernumary trainee, as a second officer, which can account for the high number of personnel on the flight deck. On larger types this is even more so. The second officer should not be confused with the Russian term "second pilot" which can appear in accident reports, which is actually their expression for the FO, the captain being the "first pilot".
The aircraft in question does appear to be a glass-nosed example with a navigators station in the glazed nose, which was a feature of the earlier 134s and not incorporated on any export models which had the weather radar there instead (note "export" meant mainly to Eastern European Comecon countries). Access is through a curtained small access hole ahead of the throttle quadrant between the pilots. At least one hijack in hand on the flight deck has been foiled by the navigator suddenly appearing through there to the surprise of the perpetrators ! Despite the great view ahead it must be a claustrophobic position to have to work in.
