| Nebs , OTH | I think the laminar flow control could provide serious solutions to range and efficiency issues, so it's a bit of a shame that this project never fully developed. 09/19/2005 @ 11:39 [ref: 11280] |
| Larry Barker , CA | The X-21A was the first project I worked on when I got out of college in 1961. My 5 years on the program provided some great learning experiences, so I have nothing but fond memories. 06/28/2005 @ 22:31 [ref: 10614] |
