On the 4th mission which is the first thunderbird 2 mission. You shoot
all of the red buildings which gain you extra time but you have to
shoot them anyway.

There is a white box behind you, which you must shoot it then go up
through the opening then go to your left then there should be an opening
in the wall go in to it and there should be a white box which you shoot.
then you go up a bit and go through the opening then you go down then to
your right and there is a red building which you shoot. Then you go
back the way you came but go up instead of going through in to the
opening then to your left then you find an opening and go up it. go to
the right when you get to the top and there should be a white box shoot
it. There are another 5
