The first F-16XL, ship no. 1 was reflown on March 9, 1989 and delivered to the Ames-Dryden Flight Research Facility at Edwards AFB. This aircraft was modified for laminar-flow studies, with an experimental titanium section on its left wing (called a glove), with millions of tiny laser-cut holes (typical 2,500 holes/sq inch and 5 sq feet of holes).

Philippines cleared to buy F-16s at estimated $5.6B The United States has officially approved the sale of 20 F-16 Fighting Falcons to the Philippines as part of a $5.6 billion weapons package.

The aircraft features a 'cranked arrow' wing for improved subsonic and supersonic flight, semi-conformal weapons carriage for reduced weight and drag, and fly-by-wire complete electronic flight control system.

Modified as F-16XL/A with cranked-arrow wing and flew for the first time as F-16XL-1 on July 15, 1982. Flew 437 flights as the XL with the USAF.

The F-16XL design's ailerons were modified by extending the tips 1-2 ft., and adding an outboard area forward of the hingeline. Since LMTAS has been awarded the contract to develop the F-35 as the next multirole fighter of the USAF and a lot of it's allies, futher development of this version isn't expected anymore.

They were assigned a new NASA serial number: F-16XL/A received #849 and F-16XL/B received #848. Both F-16XL aircraft are currently stored in the NASA hangar at Edwards.

The Falcon 21 or F-16AT was proposed in 1990 as a low-cost alternative to the ATF. It was to use the basic F-16XL design, along with one of the proposed ATF engines. However, it was to use a trapezoidal delta wing rather than the F-16XL's cranked-arrow wing. CK-1 test bed fighter

The pilot survived unharmed but very shaken. It was shipped to General Dynamics Fort Worth in a C-5 and rebuilt into the first cranked-arrow F-16XL, flying back to Edwards one year later on December 2nd, 1981. It was later converted into a dual-seat F-16XL/B. First flight in its new configuration was on October 29th, 1982.
