I'm baffled at how they could pull it out..Other sources say a truck exploded, so it may have been a truck bomb?
- Missile attack? But Ukrainians are not supposed to have missiles with so long a range. Their Tochka-U are both too short range and too imprecise. US says ATACMS have not been sent to Ukraine, and in any case I doubt just one ATACMS could do all that damage. Also is improbable for a missile attack to be launched with just one missile (one wants to saturate enemy air defences) and I have seen no reports of Russain air defence launches. The missile(s) would have been tracked by innumerable radars. Improbable I think.
- Truck bomb? But it should have been a big truck bomb indeed to destroy the bridge detonating from above, and vehicles are controlled at checkpoints before being allowed on the bridge (there's even footage around the Internet of military personnel checking, supposedly, the very truck which blew up). And planting some hundred kilograms of explosive on a truck bound for the bridge from the Russian side, escaping alla controls, looks quite improbable to me.
- Special operation forces? That is to say: Ukrainian sappers reached the bridge, mined it with explosive and then bailed out before the explosion. That would explain the scale of the damage, but it's unbeliaveble Ukrainian SOF could manage such a feat under the nose of Russians. Not even if they had underwater assets able to ferry the sappers, which they don't have.
- A drone ship? Someone say a wave which can be seen under the bridge span when the explosion starts, indicates some naval asset (filled with explosives) was used for the attack. I think this would explain the damage, and recently there has been a report about an unmanned, unidentified sea vehicle washed up near Sevastopol, so not totally impossible, but yet again I think it should have had to dive underwater in order to escape Russia's surveillance, so something pretty much innovative, to say the least.
