How to save a stolen jet?

I've stolen a jet in the story mode (multiple times now). I've brought it to both hangars (red squares on the picture), but none was saved by the game.
I tried both hangars with Franklin and the one more in the south with Trevor.
Has storing jets been fixed or did I miss something? If I drive into the hangar, nothing happens. If I leave the jet, stay right next to it, save and reload, it will be gone.
I'm playing on PC.
Best Answer
I found that with Trevor's second hangar, if you steal a fighter jet and park it as far back in the hangar as possible, then steals another and park it in front of that one then they both save and the one in the front respawns.

Answer 2
I just stole a jet from Los Santos Airport and flew it to the Trevor's hangar (the bigger one) and it got saved somehow, even though I blew it up. Now I can fly with it anytime I want because it always respawns. Try for yourselves!
