Good question I've been trying to find this answer myself someone please answer this question.

i don't want to win best answer, i just wanna post here to keep a record.

steal bank records: illegal transaction records
ransom a businessman's kids: porsche 911

You get the prop plane from Steal An Air Freight Delivery under Capo (Levels 25-34). I didn't get it the first time, but I got it twice after that.

That's good to know where the loot is but I tryed 10 times even with the extra chance to get this loot but nothing yet ouch!!!!

Sandra M- On the loot page there is a scroll bar on the right side of the Loot box. Scrool down and your items should be there. Hope this helps.

New loot is part of collections and can be added to ur vault
So far i have ruby ring and Turqoise cigar which can be added up to vault which will increase bonuses

well the concealable camera, and untraceable cell phone are from robbing an electronics store(which is on the enforcer levels), you can also get an ivory cigar from electronics store… hope that helps!!!

the illegal transactions records can be looted from doing the capo steeling bank records job…and humvee's are lootable from doing the underboss job of breaking into the armory….but i'm still clueless on the prop plane
