Just before I started with Douglas Airways in PNG one of the Pilots had a mishap at a very steep strip in the Goilalas (Erume) which resulted in the aircraft, a Bongo van,
sliding backwards off the strip into a ditch.
It was eventually retrieved back to Port Moresby at the end of a sling by Helicopter and as I seem to remember it was 'towed'
backwards!
Have a vague idea I have a photo of it arriving back at Moresby. I'll have a look in due course.
