Shots from the second leg. . . .is Czechoslovakia really this barren and flat (more or less)?
Far from it; I'm told it is a beautiful country, especially Bohemia which is surrounded by a number of mountain ranges.
There is a wealth of scenery addons, including landclass and terrain mesh, at the Flightsim Periskop site; unforunately it won't necessarily fit the period you are flying in, but it reproduces the modern day Czech Republic pretty well.
