Turbulence is expected. The occasional run-in with a bird may be inevitable. But usually, when you're in a jet airplane, you don't expect to crash into an elk. But that's exactly what happened yesterday, as a Canadian Forces Lear-jet burst into a flames after colliding with an elk on a runway in Oregon. Luckily the crew of four managed to escape the wreckage moments before the fireball exploded. Ironically, the airport had planned to install a fence next summer to keep out the wandering herds of elk that inhabit the area. (Sorry... I can't help myself. There's just something I find funny about an airplane crashing into a elk.)
