Extradition, there are TWO Lazer jets parked back in Sandy Shores that will take off the second you reach Ft. Zancudo. I backtrack, grab a Jet. If you can't land it on the highway to grab the briefcase just parachute down.
Pick up your Buzzard and blow up the Lazzers so they dont follow you, then take out the Titan and DA, Buzzard is easier to land on road grab briefcase and fly to Martins. No parachuting.
There are no (0) missions that a Lazzer or a Tank make easier or faster.
Base Invaders can be done by ONE person. In a car.
Use the Jester or something with a bulletproof back window.
Do jump into base, use stick bombs or grenades, destroy Jets then pull up RIGHT NEXT TO the Cargobob. Hop out and hop in, simple as that. Really one of the easiest missions if done this way.
This, but use Ron's plane & land by Amunation store outside fort..
call mechanic for fast car...
proceed as above except when you land you wont have to get in and out of the plane..
You can use a Buzzard for both, which certainly makes Death from Above quicker. Base Invaders used to be quicker but continually respawning enemies with the deadliest of aim slow you down.
