Sycamore
Helicopters are sometimes known as "whirlybirds", but they're not really airplanes in the same sense. I believe what you're thinking of is actually the gyrocopter.
The Sycamore (Acer pseudoplatanus) is a broad leaf tree that produces winged fruits. We used to call them helicopters because they spin as they fall through the air. Their proper name is samaras.
yes. you cannot do it freely, but if you use EM radiation, or vacuums, you can. (airplanes and whirlybirds use vacuums) a whirlybird has a huge propeller on top, and when it sucks the air under it, over it is a vacuum. something has to fill this vacuum. thus, the whirlybird is the closest thing to this vacuum. whirlybird fills vacuum. helicopter is the new name for whirlybird. but when it was invented, it's name was whirlybird.
The tree that produces spiky balls is the sweetgum tree.
Some common nicknames for a helicopter are copter, chopper, hook, stick buddy, huey, helio, helo and whirlybird. Helicopters were used for medical evacuation but they are now the primary vehicle for air assault.
