I can't believe amount of cr@p written here by presumingly Polish posters. Crash is the tragedy. When it comes to the rest, make your facts right:
1. Both VIP 154M, reg 101 and 102 were built in 1990 and delivered new to Poland, later avionics was upgraded. They are same age as US VC25 (Air Force One).
2. 154M is not very economical airplane for airlines, but it is technically sound and reliable aircraft.
3. ATC offered them first divert to Minsk, later when handled over to Russians, they offered to divert to Moscow.
4. It looks they've attempted 4 approaches. There is no ILS at military Smolensk-North.
