My comment:
(a) 20,000 pounds is about ten tonnes.
(b) Please take notice that this attack helicopter that was featured in the
2001 film "Black Hawk Down"
Sikorsky S-67
http://en.wikipedia.org/wiki/Sikorsky_S-67
is NOT the same as UH-60 utility helicopter that US is selling to Taiwan.
UH-60 Black Hawk
http://en.wikipedia.org/wiki/UH-60_Black_Hawk
Both are called Black Hawk and both manufactured by Sikorsky.
