Not sure which aircraft this is, a 'beaver' or an 'otter'. These aircraft needed about 650 feet of runway to take off. We only had 625 feet, on a hill so half the strip was uphill, the other half downhill, with a 6 foot berm at both ends. These guys really had to grunt to make it off. As you can see, we were located right at the end of the strip and several times thought we would get 'punched out' by one of these guys!
