I need help with the Antonov 12

[a random guy]

Hi So i am pretty new and i was wondering how to keep a car in the an-12s cargo hold without it slipping out of the cargo hold on takeoff. I tried putting the handbrake on the carand i got very close to pulling it off. if anyone knows how to pull it off then please tell me. here is the link to the plane http://archives.rigsofrods.net/old-forum/forums/118-Flying-machines/120612/page-0001.html

If you press O in the Aircraft with the vehicle inside then it should secure the vehicle in place
