Bugged mission or am i doing something wrong?

[Cit.Zen]

I got a mission where i have to take 3 kerbals to a specific location, i made a passenger jet and took off.
I then checked the map looking for the destination of those kerbals, yet i dont have any marks for them.?
The only marks i have are 4 marks on the other side of the planet where i have to make a flyby and report...?

In the mission log it says "sub orbital flight", does it means i have to take the 3 tourist simply to high altitude, no matter where?

Also what "spleshdown" means? i have to test a decouler at spleshdown, how do i do that?

Sub-orbital tourist/VIP contracts aren't location specific (apart from the planet obviously). As long as you get them above the atmosphere with the periapsis still within the atmosphere the contract parameters should be fulfilled.

Splashdown tests have to be conducted in the water so fly or drive the part into the ocean and then perform the test.

As the above poster said. You need to launch a craft (plane or rocket) that takes the passengers above 70,000m without orbiting them. (You can orbit but it's a waste of fuel and effort unless you need to do so for another contract as well) 

Once they're above 70k you'll get a "parameter complete" message in your contract window and you'll get a "Contract complete" once they are safely back on the surface. The landing point can be anywhere.

Splashed down is anywhere in one of kerbin's lakes, rivers or oceans.
