15.4.1989 the crash of the Mig-21MA 2613 (kpt. Karel Procházka). Ended practicing the higher techniques of flying in a while, when the led lights up fuel in the tank left 550litrů. The aircraft was located about 5-7 minutes flight from the airport, the pilot ejected at a height of 50-100m in the fourth turn before landing with no landing gear extended landing gear. The aircraft touched down about a mile before the threshold of VPD due to lack of fuel. Between the piles 4.slp is supposedly a competition for who will land with less amount of fuel in the tanks (another version of "competition" is that it was about the maximum length of flight time). For the cause of the crash identified the pilot's lack of discipline – did not check the amount of fuel.
