Hello Kaki
It is amazing how much we learn from all the various primary (researchers) and secondary sources (ordinary people like myself) and even more amazing how little we know when we stumble upon things like the image you have posted! Let's hope some of the experts here will pull one two more images of the same event and share with us markings of the aircraft & complete shape of the aparatus!
Best,
Milos
