Cool Video…good find Robb…I wondered about that myself (about the mains as deef pointed out) I figured they pulled the breakers maybe. Thanks for the education…learned something new.
According to that the body trucks should have come down with the nose.
The Landing Gear consists of four main gear trucks, consisting of two body gear and two wing gear, each with four wheels and a nose gear with two wheels. Hydraulic power for normal Landing Gear operation is supplied by two independent sources, system 1 for the nose and body gear and system 4 for the wing gear.
The G1 has speedbrakes, they are the main gear. Separate handle, if you use them and then put the gear down the speedbrake handle retracts automatically. If you use them and don’t lower the gear it takes full power to taxi to the FBO.
The buttons next to the gear handle are mark Nose/Body and Wing to manually drop gear(. Hmmmmm… However it works, it’s a good thing they didn’t forget to drop the mains, or that video would have been really entertaining.
