The P39 has wires attached between the tips of the wings to rear tail of the aircraft. Why do they need these and if they are broken what will happen?

Also just wondered about the unique design of the p38. What advantages does the design give it?

They are aerial wires, various aircraft carry them in different configurations, such as from the mast behind the cockpit to the tip of the fin etc........ you will find them still on some modern Aircraft, the RAF chinooks have HF ones, even a lowly Cessna 152 carries one from the fin to the cabin roof http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

Regarding the P38;

- a <span class="ev_code_RED">twin-engine configuration</span> has obvious implications for reliability- if one engine fails you could probably limp home on the other;

- while most twins tend to be very much heavier than singles of the same basic type (ie, fighter, fighter-bomber, etc.) the Lightning is mostly empty space- built light enough that the <span class="ev_code_RED">power-to-weight ratio is better than most singles</span> (it has great acceleration and good manoeuvrability);

- the P38 has <span class="ev_code_RED">nose gun/cannon</span> without the need for an interrupter gear to avoid the prop- no weight penalty and no torque effect from gun recoil;

- the Lightning has "handed" engines- the two engines spin opposite of one another so there is <span class="ev_code_RED">no engine-induced torque</span> under normal conditions; as well, gyroscopic effects in singles tend allow the plane to turn well in one direction but poorly in the other- the P38 turns the same in either direction giving it an advantage when in a defensive turn, and finally;

- <span class="ev_code_RED">you can see as close to 360 degrees as is possible</span> and even see an enemy approaching from the low six-o€clock position- the Lightning has an incredible front office!

I'd still prefer a P-R3 over a P-38.

Also, it'll run 100% throttle for about a half an hour on 1 quarter of a tank without overheating or running out of fuel. Usefull for intercepts and the like.
