Why do two helicopters flying together?

Can any helicopters fly upside down?
In general, a helicopter may be able to fly upside down for short periods of time. However, inverted flight is never recommended for long-term use. Helicopters can fly upside down for a short amount of time when they are performing a loop. The things helicopters can do as opposed to airplanes are astonishing.
Why do some helicopters take off backwards?
Helicopters take off backward to allow the pilot to keep the helipad in sight in case they need to re-land in an emergency. When taking off vertically, the helipad disappears out of sight around 30ft to 50ft up, backing up allows the pilot to keep the helipad in sight through the chin bubble window.

Is it possible for a helicopter to fly upside down?
Yes, helicopters can fly upside down, and no, they can’t. To do it, the collective blade pitch has to go negative they can produce lift in the opposite direction.
Why is it that some helicopters can fly upside down?
A. Theoretically, many helicopters CAN fly upside down as long as they maintain what is called “positive” loading on the main rotor “head,” and have a rigid or semi-rigid attachment of blades to the rotor hub. Positive loading means that the rotor blades have to be coned AWAY from the fuselage.
Why do planes fly upside down?
They don’t rely at all on wing shape for lift. To fly upside down, a stunt plane just tilts its wings in the right direction. The way a wing is tilted is the main thing that makes a plane fly, and not the wing’s shape. The angle of attack is the angle between the axis of the wing and the direction of incoming air.
