Passengers visited cockpit before Kaczynski crash

As Polish President Lech Kaczynski’s plane streaked toward disaster, at least two passengers visited the cockpit, others may have chatted on mobile phones that can obstruct navigation instruments and an under-trained crew faced heavy fog over challenging terrain.

Those were among the details revealed today by Russian and Polish officials investigating the April 10 crash that killed Mr Kaczynski, his wife and 94 others outside the western Russian city of Smolensk. The preliminary report drew no conclusions about what caused the catastrophe.
