I thought that they had scrapped it but apparently they revived it

The flying vehicles "EKIP" will transport heavy loads and large numbers of passengers (1000 and more) to the existing airfields of continental and waterlocked countries.
It should be specially noted that the flying vehicles "EKIP" may use gas fuel (natural gas and hydrogen). Large volumes of the flying vehicle permit to locate inside it without changing the external contour large volume gas fuel tanks. Limited resources of oil (to last for 50 years) require transition of airplanes to gas fuel. However limited areas of thin wings of existing airplanes do not allow this transition. As the gas fuel occupies half of passenger compartment on airplane Tu-156 and in airplane A-310 (DASA project) the fuel occupies the whole area above the passenger compartment thus changing the external contour of the airplane and decreasing its lift-drag performances. The flying vehicles "EKIP" permit due to large volumes to locate the fuel tanks in the lateral part of the aircraft without changing the external contour of the vehicle.
