The Sovjet/Russian Mil MI-26T helicopters (NAVO-Codename Halo) are the biggest and most powerful helicopters ever to have gone into production.
They’re not allowed to fly in Europe because of their size and probably because of safety reasons. They are 40 m (131 ft) long, 8 m (27 ft) tall and 8 m wide.
They weigh 28.200 Kg (62,170 lb) and can carry almost as much. They can fly up to 295 km/h (183 mph) at 4,600 m (15,100 ft).
These heli’s were stationed in a small airport in Belgium and haven’t been used for over 10 years. They were transported in 2008 from Bierset, and the initial plan was to have them shipped to Russia. But the owner backed out.
The transportation company never got a penny for the costs of transporting those machines. They’re now gently rotting away on a parking lot so the helicopters were seized by the court and will be publicly sold.
