Slush Recce Anyone?!
If you don’t know what it is, don’t worry, as the following script and video explains.
On that exercise in Algonquin Park (see maps), the planes were moored close to land for ease of refueling, maintenance etc.
The slush is water that was not completely frozen, because a high wind moving against the shore, accompanied by heavy snow, prevents the shallow areas from freezing completely. However, you don’t realize that your skies broke this snow cover and now this snow turns to ice!! In this incident, the flight commander, Maj. Mike Henderson dutifully does his external checks and now, see video!
Lesson learned! Beware of slush! When landing on snow, do a touch and go, check that there are no dark tracks, meaning water – go up again and try to land somewhere else.
