I always enjoy the PegasusXL air-launches, so I thought I'd have a go at this one
Not been much about it on the news, the last PegasusXL launching from the last(?) L1011.
Slated for take off from Kwajalein on 27 June.
Katalyst Space's "Link" spacecraft to rendezvous with Swift and give it a boost.

Not much info about the Link spacecraft other than overall mass and size.
I've given it 3 Ion engines optimistically rated at 0.1N each, its not much for orbital maneuvers.
Also given it RCS, reaction wheel control and 30kg each of Xenon and RCS propellant.
I have no idea about its robotic grappling system, so I made something very ad-hoc!
Best I could do reasonably quickly.

Its a night launch for the L1011 and PegasusXL, so theres a lot flying-by-instruments.
Quite fun
