Northrop HL-10

In mid-1964 Northrop was contracted by the US National Aeronautics and Space Administration (NASA) to produce two all-metal wingless lifting-body re-entry research vehicles, based on experience gained with the Northrop M2-F1 wooden glider, which made more than 500 flights in 1963-64. The two new vehicles were designated M2-F2 and HL-10 and differed in under- and upper-surface fuselage shapes. First flight of the M2-F2 as a glider was made on 12 July 1966 when it was dropped from beneath the wing of a Boeing B-52 at 14235m to make a successful 306km/h landing four minutes later. The HL-10 made a similar flight on 22 December 1966. First powered flight using rockets was made by the HL-10 from a B-52 on 13 November 1968; the M2-F2 was badly damaged on landing in May 1967 and, subsequently rebuilt as the M2-F3 made its first powered flight on 2 June 1970, attaining Mach 0.8 at 16155m on three of its four XLR11 rocket chambers. Later in the programme it recorded a height of nearly 27430m and speed of Mach 1.7, while the HL-10 attained Mach 1.9 and a height in excess of 27430m. When testing ended in 1973 these aircraft had provided much information which was to prove invaluable for NASA's Space Shuttle programme.

In the 70's and 80's North American Aircraft tried to have all the engineers go metric. We filed the waste baskets with the conversions and only used english units. Soo can you please also use the english units so we can know the altitude and other english units.

Yes. It was used in the pilot episode and also a season two episode called "The Deadly Replay," where Steve Austin was asked to test fly a rebuilt version. It was called the HL-10 in this episode and the same tail number as in the above photo, "804" was visible on the aircraft throughout filming. Some weird release rights issue keeps SMDM from being released in the US, but a try viewing a few episodes here /show /the-six-million-dollar-man /-livxPfDBgfEoitS or ordering the DVD from Australia and watching on a region-free DVD player.

Wasn't this the one Steve Austin crashed & was then rebuilt as The 6 Million Dollar Man?


Do you have any comments?
