Russian president Vladimir Putin
In 2009, when the Lake Baikal Mir dive took place, Vladimir Putin was Russia’s prime minister, not its president.
Full reasoning
This sentence refers to the 2009 Mir submersible dive at Lake Baikal. Vladimir Putin was not president then.
- The Russian government’s own archived biography says Putin was appointed Prime Minister on May 8, 2008.
- Contemporary coverage of the August 2009 Lake Baikal dive likewise describes him as the Russian prime minister.
So calling him "Russian president Vladimir Putin" in this 2009 context is a title error.

The report on the 2009 Baikal dive says: “Now the Russian prime minister has added a new alter ego …” and later, “At the weekend Putin … dove … to the murky bottom of Lake Baikal.”
The Baikal Neutrino Telescope NT-200 is being deployed in Lake Baikal, 3.6 km (2.2 mi) from shore at a depth of 1.1 km (0.68 mi).
NT-200 is not currently ‘being deployed.’ It was already producing results by 2001 and the active construction now is the newer Baikal-GVD detector.
Full reasoning
The present-tense claim that NT-200 “is being deployed” is outdated and incorrect.
- A 2001 arXiv status report for the Baikal collaboration already says researchers were presenting results obtained with the deep underwater neutrino telescope NT-200, which means NT-200 was already operating by then rather than currently being deployed.
- The current official project site for Lake Baikal neutrino astronomy describes the Baikal-GVD telescope as the detector under construction today, with milestones from 2015 through 2025 and 14 operating clusters by 2025.
So the article is mixing an old description of NT-200 with the current state of the observatory. The detector now being deployed/expanded is Baikal-GVD, not NT-200.

The Trans-Siberian Railway was built between 1896 and 1902.
Those dates are too narrow for the Trans-Siberian Railway as a whole: construction began in 1891 and the all-Russian route was completed in 1916.
Full reasoning
This sentence confuses the overall Trans-Siberian Railway with one of its later segments near Lake Baikal.
- The official Transsib history page gives the “Stages of Great Siberian Way construction (1891–1916)”.
- The same source separately lists the Circum-Baikal railway chronology as 1896–1905, which is much closer to the dates used in the article.
So 1896–1902 is not the build period for the Trans-Siberian Railway as a whole. Construction started in 1891 and the continuous all-Russian route was completed in 1916.
