In a Glasflugel Open Libelle glider at just over 10,000' out on task, and quite a glide away from the airfield, I had no option.
Anyone who knows anything about the Libelle would know that the seating position can be best described as 'semi-reclining.'
There was a sickbag in the map pocket of the aircraft and it was used successfully without spilling a drop.
It was not an easy exercise in the slightest.
How I managed it and how the bag was eventually disposed of is
