The Hague is more likely than Utrecht.
V2 rocket
About the V1 I have read that V1 launch rails were not (very) mobile and could be easily spotted and destroyed from the air.
Launching from airplanes was more difficult to intercept.
I think I have also read that the gyro could not handle the G-forces of skid launching very well. Therefore it could be off course from the start.
