Appendix

Aviation Heritage Succession Fund Activities

Covering a wide range of items such as drawings, photographs, and interviews with people who worked on civil aircraft before the war.

It is intended to be collected, investigated, preserved, and made available to the public.

“Officials and family members who spent the past era of aviation breakthroughs together, recognized their importance, and kept related materials have died.

Precious photos and materials are being lost. These are valuable resources that preserve the developed aircraft and aviation culture for posterity.

This is a fact that it is not widely recognized as an important key to the future development of technology-oriented Japan.

Therefore, it is rarely subject to preservation and inheritance and in many cases only the information has been collected and valuable original materials are damaged.

To save this aviation heritage, the Japan Aeronautic Association established the "Aviation Heritage Succession Fund" on July 1, 2004.” ---- quoted from a post by the Japan Aeronautic Association
