One pilot was injured Sunday after two home-built planes crashed into one another in mid-air near Ponoka. 

RCMP say the two kit planes were flying in formation from Carstairs to Red Deer Lake at around 11:30 a.m. when they collided. 

One plane crashed into a field about 10 kilometres northwest of Bashaw. The pilot was taken to hospital with a leg injury. 

The other pilot landed his aircraft safely. 

Investigators from Transportation Safety Board have been called in to examine the events that led up to the collision.
