Hanoi school boys

Photo taken out window of taxiing C-130 on historic flight into Gia Lam Airport, Hanoi, North Vietnam in 1973 … shortly after ceasefire. Pictured is large group of young boys along with two or three male adults (teachers?). Guessing that these were children attending school at the thatched roof building in photo, and they had come out to see unfamiliar US aircraft. Not long before this, intense US bombing and North Vietnam defense thereof was occurring in this Hanoi area. Seems odd that there would be a school (if in fact this is what we saw) in such close proximity to an obvious military target. Many in this group had raised arms; could not tell for sure if it was friendly waving, or angry fist pumping toward us … I suspect the latter.
