All bridges in Kyiv and Boryspil and Kyiv airports were mined to prevent Russians from seizing the capital — the Minister of Defence of Ukraine in the documentary Year by Dmytro Komarov

Oleksii Reznikov says that upside-down vehicles were placed at the aeroports, and the runway was flooded with oil, making it impossible to land the troops.

All bridges in Kyiv were mined to cut off the possibility of crossing from the left bank to the right bank in case of a breakthrough by Russian troops.

The head of Ukraine's Main Intelligence Directorate, Kyrylo Budanov, said that the Russians had planned to raise the flag over the Presidential Office no later than three days after the start of the full-scale invasion with a change of leadership.

The Russians' only plan was to land airborne troops and quickly enter Kyiv. Then, in their view, Ukraine's leadership would flee. If not, they would have destroyed it and "extinguished the sporadic manifestations of resistance" in no later than ten days.

Defence Minister Oleksii Reznikov notes an attempt to seize the Pechersk Hills was likely, as it is convenient for helicopter landings. 

Four days before the start of the full-scale invasion, Sberbank of Russia branches in Ukraine bought up all the cash they could at the highest rate. Kyrylo Budanov said they had accumulated the cash in vaults and "waited for their own people to arrive."
