I just found this video on YouTube.
According to the YouTube user, a Beechcraft Bonanza took of June 10th, 2009 to videotape a friend flying an Aero L-39 Albatros. Due to bad weather with low visibility, the Bonanza came very close to terrain. How close it really was, you can see on the damage of the plane in the end of the video.
Gosh!
That was scary!
