Some spectacular lies from the Russian Embassy there! For an aircraft that was designed and built specifically as a military strategic heavy-airlifter Vlad the fibber is simply parroting the standard Russian vranyo. (An official statement that everyone knows is a barefaced lie, including the people that issued it - it's an official means of ending discussion of a subject)
"When asked if the jet would be used in its war against Ukraine, if returned to Russia, Proskuryakov said “it’s not possible.” Vranyo! "Of course it's impossible, there isn't a war with Ukraine!" Of course! It's just a 'special military exercise' isn't it?
"It is built and used for civil purposes only. It does not transport any military troops or equipment.” Vranyo! Just read the first line of the Wiki page for a start, leave alone the rest...
And of course it gets the proper maintenance. It was probably overhauled in the factory a couple of years ago and has been kept in fuel, oil and (reluctantly) tyres ever since. It needs nothing more for a year or two. Well, bar the odd weekly engine change.
I trust Canada ensures this machine remains where it is until it can be sold/scrapped as war reparations for Ukraine.
