A helicopter has collided with an ultra-lightweight airplane over the Spanish island of Majorca, killing seven people.

Three adults and two minors were believed to be from a German family onboard the helicopter while two Spanish citizens were on board the aircraft.

According to the BBC, the debris landed near Inca and the helicopter involved was a Bell 206 L3 LongRanger, operated by German airline Rotorflug.

The plane involved is an ultralight aircraft, which can accommodate up to two seats.

Local newspaper Diario de Mallorca noted that both the private-based vehicles collided mid-air over the Inca Hospital.

The helicopter had taken off from the Son Bonet aerodrome while the aircraft took off from the Binissalem aerodrome.

The reason for the collision is still unclear, read a statement on BBC.

German aviation authority and air accident investigators are currently examining the case to determine the cause, besides the Majorcan authorities.

Spain’s Acting Prime Minister Pedro Sanchez was quoted by Reuters as saying: “My solidarity and love for the families of the victims that lost their lives in this tragic accident.”

The Government of the Balearic Islands has announced three days of official mourning in memory of the Inca plane crash victims, in the autonomous community area of the Balearic Islands.

Last month, GippsAero GA8 Airvan crashed in northern Sweden, killing all nine people on board soon after take-off from Umea Airport.
