i join the others in wishing dan-san a speedy recovery. i always enjoy his authoritative contributions to the forum.
i just got back from los angeles where i had a chance to visit chino airport displaying the DrI and Brisfit (replicas) and Hanriot flown by Nungesser. Also bought "The Ghosts of the Great War
" with breathtakingly vivid color photos (WWI replicas in flight) by Makanna.
