  1. Let me put my understanding of the situation to you. Two things seem given: First, the deformation on the cylinder suggests contact between the side of the dome and an obstacle. Second, the almost circular shape of the crater requires a vertical impact or explosion. At 30-50m/s the cylinder moves relatively fast. Anything that hinders its path in this movement but does not deflect it can only cause longitudinal scratches, but no lateral imprints. If the cylinder actually fell, it was stopped by the balcony, because it did not fall into the lower level. The only way to get from that vertical standstill to a lateral contact is to tip over onto the grid. In this case the the force wouldn't be sufficient. Furthermore, the grid would have to be next to the crater with the cylinder on top of it. A bounce or a lateral contact against the wall can be excluded, because such a contact would have left considerable / visible damage. Except for the fragment patterns from any explosion, however, no damage can be attributed to the cylinder. Furthermore, the bouncing should have taken place after the formation of the circular crater, because (as we know from hole at location 4) this bounce can only happen to a very small extent and the energy after bouncing could neither create such a crater nor damage a bed. Even if enough energy would remain the lateral bouncing cylinder would certainly not create a circular hole of its double diameter without more excessive damage to the surrounding walls first. Therefore, the assumption that these scratches were created as lateral bumps on the way between the roof corner and the crater (or even after the creation of the crater) is similar to squaring the circle.
