Another Russian TV report
Here is another Russian TV report which gives an idea of the depth of the excavation as well as some close ups of parts of the wreckage and documentation, including pilot ID with a faded photo –

And other ones with some different material here – https://iz.ru/737872/video/samolet-vremen-vov-i-ostanki-letchika-nashli-na-stroike-v-peterburge
and here – https://www.1tv.ru/news/2018-04-28/344732-v_peterburge_nashli_oblomki_istrebitelya_vremen_velikoy_otechestvennoy_s_ostankami_letchika_na_bortu
the final report is interesting as it appears to include an extract from the previously mentioned book describing the incident that led to the loss of the aircraft and perhaps to have relatives at the site (I don’t speak Russian so am guessing somewhat?)
