Hi I'm new to Wikipedia. I really don't know enough about correct Wiki format to properly add to the article but just wanted to share this information to anyone who might want to add this. Thanks!

"In 1989, the price of an individual Williams X-Jet unit was described as being "more than a Jeep, less than a helicopter", dependent on the size of the production run."

The thrust to weight information is incorrect. I do not know the correct value, but no vehicle with an empty weight of 400 lbs can have a thrust-to-weight ration of 4.11 with an engine only producing 600 lbs thrust. 1.5:1 is a more likely number.

I double-checked the specs on the museum display and it clearly says that the thrust to weight is 4.11:1. Can someone find the correct number and post it with their source? Otherwise, I am going to change it back to 4.11:1. Also, what's the source of the change from 10,000 ft ceiling to 11,000 ft ceiling? I can't find confirming info. --JimCollaborator 04:42, Mar 16, 2005 (UTC)

If the machine plus operator weighed 550 lb, and the engine produced 600 lbf thrust, then the thrust-to-weight is 600/550 = 1.09:1.

4.11:1 is the thrust-to-weight of the engine, not the aircraft. (ie, 600/146). --Rlandmann 12:35, 16 Mar 2005 (UTC)

Ok, that makes sense (to my non-engineering mind). What about the change to the 11,000 ft ceiling? --JimCollaborator 17:46, Mar 17, 2005 (UTC)

Typo! Thanks for the catch --Rlandmann 01:26, 20 Mar 2005 (UTC)

[edit] akira

it should be noted that katsuhiro otomo probably used these as a basis for the flying platforms in "akira", so maybe there should be an "in art" entry

Maybe a mention on the Akira (film) page, but probably not here, I would think. --JimCollaborator 08:05, Mar 16, 2005 (UTC)
