If you fly to the left right away you can take out two dots, a van and a bike, for the bikes it is best to swoop and kill the first time they see you, because if you don't they just keep firing at you and you blow up
anyway look at the bikes and head at them from right behind or infront... that is what I did.
anyway I just did the Casino Heist for Woozie, has anyone glided over to the swat helicopter? cause I always fall short about 2 meters
oh a different note, I have stolen 6 patriots and 4 rhinos from the restricted area
