Nerdy but interesting...
For those wondering why a Boeing 747 is used and not another plane...
The Boeing 747 was designed from the word go, to be able to carry and deliver a spare engine to other Boeing 747s elsewhere in the World. Boeing thought ahead and built an extra engine mount into the left wing structure between the other engines and this is what Virgin orbit is using to carry the rocket, and why this plane is used.
