N1-6L was launched on the night of 26-27 June at 02:11:52 Moscow time. All thirty engines ignited successfully, and the first 5 seconds of flight were nominal. But from the first motion off the ground the booster began a slow axial rotation. By 14 seconds after launch this had reached 8 degrees per second. The booster's gyroscopic platform commanded an AUD - energy engine shutdown. But the command was not accepted by the control system - as agreed with Barmin, to save the launch pad, it was blocked until T+50 seconds. By that time the booster had rolled 60 degrees, and as soon as the filter was removed, all 30 engines were shut down. The booster crashed 30 km downrange. Without the signal blocking the booster would have crashed 1 km from the pad, seriously damaging the launch complex. The viewers remembers at V-2 crash commission at Kapustin Yar in 1948., where Pilyugin declared he favoured rocket failures, since nothing could be learned from a nominal launch. But this did little to diminish the gloom, which was exacerbated by the space community attending Isayev's funeral a day later.
