Tupolev Tu-144 LL
In the early 1990s, a wealthy businesswoman, Judith DePaul, and her company IBP Aerospace negotiated an agreement with Tupolev,
NASA,
Rockwell and later
Boeing. They offered a Tu-144 as a testbed for its High Speed Commercial Research program, intended to design a second-generation supersonic jetliner called the
High Speed Civil Transport. In 1995, Tu-144D No. 77114 (with only 82.5 hours of flight time) was taken out of storage and after extensive modification at a cost of US$350 million, designated the
Tu-144LL (where LL is a Russian abbreviation for Flying Laboratory,
Russian:
Letayuschaya Laboratoriya, Летающая Лаборатория). The aircraft made a total of 27 flights during 1996 and 1997. Though regarded as a technical success, the project was cancelled for lack of funding in 1999.
