I know that many people disagree with me on the importance of flying visually instead of staring at the pretty glass panel, but:
Sun News : Blind spots caused planes to collide mid-air: TSB
An investigation into why two planes collided in mid-air over Pemberton, B.C., last year has found both pilots were in each other's blind spots and wouldn't have had time for emergency maneuvers until the last moments before collision.
The Transportation Safety Board said in its report on Thursday it was clear skies during the noon-hour on June 29, 2013, and winds were calm.
Visibility, however, was the biggest problem due to the positioning of the planes at the time, according to the TSB's findings.
This is exactly what killed Bobby Younkin and Jimmy Franklin at Moose Jaw.
