Ezra, I think you need to contact the author of the article and pose that very question to them. I would think that anyone connected with MIT should know better?
Let us know what they say.

Since the kilogram is the base unit of mass, what the heck is it doing here purportedly describing thrust? What is the correct way to express thrust? How is it properly defined, and how the heck do you measure it? Ezra --- Incoming mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
