Yes and no Yarbles. Belly landing is not a problem in itself, but it can have some disadvantage... if you dont make it on the runway for any reason, you have no way of correcting it. Also, most special events are 1 live and require you to land and rearm instead of landing and getting a new plane. Also, if you are a little too fast, a belly landing has higher risk of blowing you up.
As for Landing: Anywhere you get a "landed sucessfully" message, you get full points for the sortie. When youre in a plane and on an airfield, you can land successfully anywhere on concrete... damage is not taken into account. You can always test where you get what OFFLINE.
For Vehicle bases and Vehicle landing, things are a little more complicated. Safest spot to get a landed successfully on is between the hangars on VBase. If you are damaged and there are enemy vehicles close, you do not get a landed succesfully. Also, you can land vehicles at the spawn points (yellow arrows on map), again provided you have no damage and there are no enemy vehicles around.
Points: You always get points, no matter the outcome of your sortie. But if you do not land successfully, you only get fractions of the points... check the help page on Scoring and Perk points for the listed multipliers.
The radar tower needs 250 pounds to destroy (strafing with cannon, rockets or bombs) and has a default down time of 2 hours. How long it actually stays down depends on the state of the radar factory and player supplies. Check the help file on Strategic targets for more detail info.
Landing: Practice in planes that are easy to land first. Hurri Mk2, FM2 and P38 are my usual recommendations. Make sure you know where the speed indicator and climb rate indicator in those planes are, as you need them to monitor your approach.
Drop down to about 1000 feet above ground, line up on the runway from far out. (Icon range is a good starting point, it gives you enough time for adjustments and corrections).
Reduce your throttle to slow down (throttle idle at first!), as soon as you are able to, lower gear and full flaps.
If you notice that you are way too fast (over 200), you can
sideslip as mentioned above (use full rudder to one side and keep the plane level with aileron input) or make a series of highG hard turns.
You want your speed to be about 120-150 mph approaching the runway. Do not point your nose down at the runway... if you aim for it, youll hit it - usually pretty hard
. Aim for the far end of the runway instead.
On finals, youll need to use your throttle to control descent rate and your Elevators to control speed. That means: If you put your nose down, you will increase speed. Keep the nose high (flaps help you with that) and adjust your throttle to control sink rate - that takes a little practice, but it sounds a lot more complicated then it really is. Usually it is enough to hold the nose high and be throttle 0.
Your sink rate at touchdown should be no more then 1000 feet per min. On the gauge that means the needle needs to be between 0 and -1. Touchdown speed at 90-100 mph.
Right before the wheels hit the ground, throttle up a little bit (=flare).
Let the plane roll for a while, slowly pull back to 1/2 on your stick to lock the tailwheel (like on takeoff), then apply wheelbrakes.
Do not worry if you miss the runway on the first landings. Thats not a problem, as you can always taxi back on concrete when youre down. The most important thing is to get the plane down without prop or gear damage.
If you catch me online, holler my way, i can show you a landing or two and help you with yours.
