It's a monster.
Although not a Caspian Sea Monster.
The problem with these concepts (apart from hanging a 250 tonne rocket off a large wing) is that the you can't just tip a rocket on its side.
Rockets are tremendously strong in 1 axis while the rocket this carries has to be very strong top-to-bottom (while it's hanging from the wing) and equally strong when the engines fire up.
Also the aircraft does not give you anywhere near the velocity of a stage. So having spent a metric shedload of a cash to build your humougous aircraft you still need to build a 2 stage rocket anyway.
If you could build a rocket that was SSTO (if launched from this aircraft) that would be a major breakthrough in the SoA.
