Sulphur
Phosphorus (especially white phosphorus) is a nonmetal that can spontaneously catch fire (VERY reactively) in air.
Since air is not inherently flammable, there is no speed at which a helicopter blade would catch the air on fire.
Hot dry air alone is unlikely to cause wood to catch fire. However, if the temperature is high enough and there is an ignition source present, such as a spark or flame, the hot dry air can contribute to the wood catching fire more easily due to its reduced moisture content.
yes, if the wood is dry and the air is hot enough

When sodium and potassium are exposed to air, they react with the moisture in the air to form oxide compounds. This reaction generates heat, which can ignite the metal and cause it to catch fire. To prevent this, sodium and potassium are usually stored under mineral oil or kerosene to protect them from moisture in the air.
It can be burnt, but not catch on fire.
