There is a tyre here but i hid it,u can see that the air some escape through the top but some hit the tail and got nowhere to go and then flow through the bottom of the tail

Here you can see the same shape of air circulation from the side pods.
Oh,and i forgot to upload the body contour of the sidepods.
But,they all blue in colour which means VACUUM!
Darn,should i sacrifice the mass or not?
Vacuum clearly add drag but hey they decreased not increase.
Weird
