do anyone know how to get pass that San Andreas mission where you have to land by the dam?

Question

You have to fly that big airplane around and it has a yellow marker on the map. But I never see it on the ground...

Answer 1

You have to jump out fo the plane with a parachute and land in the marker.
Dam And Blast
CJ is going to shut off the power to the city to aid in their plan to break the bank at Caligula's. First you'll need to get to the airport and grab a plane as you'll be parachuting onto the dam. Make your way to the airport and enter through the gates, then drive to the runway where you'll find a parked plane. Get in it and fly to the dam. You need to be pretty damn high before you can jump, so fly around in circles while gaining altitude. When you fly through the corona, hit triangle to bail. After the cutscene, you'll be freefalling. Almost immediately hit circle to use the parachute. Point yourself towards the red circle and let yourself slowly glide to earth. Just as you approach the red circle on the ground you may need to pull back the analog stick in order to land in the right place. Once you land you'll see another cutscene telling you to sneak into the dam. You'll find a knife by some containers which you need to pick up and use for stealth kills. Crouch and walk along the dam until you reach the knife. Pick it up and use it to stealth kill the two guards. Monitor their routes using the radar and sneak up behind them. Once you've disposed of them, head up the steps and into the red circle. Now you need to sneak around this area and stealth kill the five guards. They're pretty stupid, and even if they see you, a few knife stabs will kill them before they sound the alarm. Kill them all, preferably without being seen then once they're dead, walk up to each generator and push triangle to plant your charges on them. Once you've done all 5 generators head to the exit. After the cutscene Carl will dive off the dam.

Mission Passed!

Answer 2

Look at the map marker, if it is a triangle poiting up the corona you fly through is above your, if it points down you are too high. Just get out of the plane when it tells you and fall toward the pink marker which will appear after reaching the first marker (the corona in the sky) Deploy your chute early (not to early or you'll be up there awhile) and circle around. You can cut the chute loose with one of the buttons and drop the last few feet when over the marker. There is a chute in every aircraft (At least for me) just getting into a plane will give you one. Not too sure about Helis. There is a chute on top of the really tall building in Los Santos and a door that will take you to the top at ground level. So you can get practice in there, kind of fun too, though it takes a few minutes for the chute to respawn sometimes.

Answer 3

try flyin real high....
if i'm not mistaken, the corona is nowhere on the ground
