In 1951, Brazil was supplied with thirteen B-17s under the provisions
of the 1947 Rio Pact.  Six were tranfwerred in 1951, five of which 
were SB-17Gs and the sixth was an RB-17G.  Seven more were 
transferred in 1954-55.  All of these planes were used for search and
rescue or for photographic reconnaissance.  In 1955, the survivors
were assigned Forca Aerea Brasiliera serial numbers between 5400 
and 5411.  These planes were all withdrawn from service in the mid-
to late-1960s.  Three of these planes have survived, two of them
on display in museums and a third in storage.

The serials of these planes were as follows:

Shortly after the new nation of Israel was formed, the new Israeli
government surreptitiously acquired four B-17s by purchasing them
on the commercial market via intermediaries.  They were ferried
across the Atlantic one step ahead of the customs officials.
One was interned by the Portuguese when it landed in the Azores
for refuelling, but the other three made it to Czechoslovakia whey
they were fitted with hand-held machine guns and loaded with
bombs.  On their way to Israel, they passed over Egyptian targets
and unloaded their bombs.  The three Israeli B-17s served in the
1948 war of independence and again in the 1956 war with Egypt over
Suez.  They were withdrawn from service in the late 1950s, and all
were scrapped in 1961.
