How lucky were they to just make it over the highway overbridge . Mind you AN2s are very special aircraft, when visiting my son in Czech republic I often go and watch the goings on at his local airstrip. Usually the AN 2 is doing its paradropping and can clearly be seen going backwards on a windy day at afew thousand feet . Also no two landings seem the same , sometimes rolling out some way as they are big and heavy and sometimes seeming to stop almost as they touch down.
One of those cases where speed isn't an advantage for some tasks. reading a book about the U Boat war in WW2 one has to think of the Swordfish - a suicide job attacking conventional warships but its slowness and therefore ultra short take off and landing on small escort carriers its big engine bi plane layout made it literally perfect for convoy escort duties as no helis back then and anything modern (for the time) would have struggled with the escort carriers dimensions.
And the AN2 and Swordfish reallyare quite alike
