Mirrored Airplane gets a groove

Here is my first mirrored airplane. Now when I apply the Mirror and apply the SubSurf, the two parts (original and mirror) get smoothed out separately and there is a grove that appears between both… I tried removing duplicates etc… but in vain
can some one help?

You need to delete the faces that are on the INSIDE of the airplane, so after mirroring it looks like a hollow shell instead of two halves put together. (Hope that makes sense; I can upload a blend if you like, but it’s pretty straightforward) cheers

wow… thank you… it worked :slight_smile:
