The MiG-29UB Fulcrum-B has limited operational capacities, since it has no radar. Here, 787IAP MiG-29UB N50903014007/33 taxies by on Finow. Although it was the day of final departure and with destination Ross in Belarus, this UB doesn't have additional fueltanks. Maybe it went to another unit closer by. We will probably never know for sure...
