It indeed is the createvehicle command which you must use if you want to CREATE the planes. You can also insert them in the editor to some remote location and then setpos them over the sea to 5000 kilometers height. Also you can use the setfuel command to stop the planes from moving before they are setpossed.
If you go with the createvehicle command, you must also assign pilots to the planes by either inserting them in editor and then putting them in the planes with the moveindriver command, or you can go ahead and create the pilots too.
