On Christmas Day 1907 Aarón Félix Martín de Anchorena
(1877-1965) and Jorge Alejandro Newbery (1875-1914) inflated “El
Pampero” with cooking gas in Buenas Aires, Argentina, rose to 2000
feet altitude and drifted for two hours across the Río de la Plata to
land at a ranch about 30 miles away in Conchillas, Uruguay. This was
the first flight across the Rio de la Plata.
Aaron de Anchorena (1877-1965) is known as the Father
of Argentine Aeronautics. He appeared in 1968 on a stamp issued by
Argentina to mark the 22nd Aeronautics and Space Week (868). He and
Jorge Newbery, among others, founded the “Aero Club Argentino” in
1908. Newbery was honored on a stamp issued by Argentina in 1964
The balloon, “Pampero,” was named for the cool
Pampero wind, blowing on the flat plains of Patagonia and the
Pampas after a cold front.
Two people Jorge Newbery and Aarón made the
flight across the Río de la Plata in 1907 although the picture
on the stamp shows only one.
