Air-launched rocket drop zone known to have been used for 6 launches from 1996 to 1999, reaching up to 834 kilometers altitude.

1996 November 4 - 17:08 GMT - Launch Vehicle: Pegasus. Pegasus XL F14 FAILURE: The rocket functioned perfectly but the separation system failed to release the payload. HETE Spacecraft: HETE. Agency: NASA-GSF. Perigee: 487 km (302 mi). Apogee: 555 km (344 mi). Inclination: 38.00 deg. Period: 95.00 min. The High Energy Transient Experiment (HETE) was an international mission led by The Massachusetts Institute of Technology (MIT). Its prime objective was to carry out the first multiwavelength study of gamma ray bursts (GRBs) with UV, X-ray, and gamma ray instruments. A unique feature of the mission was its capability to localise bursts with several arcsecond accuracy, in near real-time aboard the spacecraft. These positions were to be transmitted to the ground, and picked up by a global network of primary and secondary ground stations (SGS), enabling sensitive follow-up studies. However the satellite was never released from its payload fitting. Although signals were received, the solar panels could not deploy, and it went silent after a few days when its batteries ran down.

1997 October 22 - 13:13 GMT - Launch Vehicle: Pegasus. Pegasus XL F18 STEP-4 Spacecraft: Eagle. Agency: USAF STP. Perigee: 432 km (268 mi). Apogee: 500 km (310 mi). Inclination: 45.00 deg. Period: 93.80 min.

1997 December 23 - 19:11 GMT - Launch Vehicle: Pegasus. Pegasus XL/HAPS F19 Orbcomm A1 Spacecraft: Microstar. Agency: Orbcomm. Perigee: 812 km (504 mi). Apogee: 823 km (511 mi). Inclination: 45.03 deg. Period: 101.26 min. Plane A. Ascending node 297.7 degrees.

1998 August 2 - 16:24 GMT - Launch Vehicle: Pegasus. Pegasus XL/HAPS F22 Orbcomm B5 Spacecraft: Orbcomm. Agency: Orbcomm. Perigee: 813 km (505 mi). Apogee: 824 km (512 mi). Inclination: 45.00 deg. Period: 101.28 min. Plane B. Ascending node 61 degrees.

1998 September 23 - 05:06 GMT - Launch Vehicle: Pegasus. Pegasus XL/HAPS F23 Orbcomm C1 Spacecraft: Orbcomm. Agency: Orbcomm. Perigee: 811 km (503 mi). Apogee: 825 km (512 mi). Inclination: 45.01 deg. Period: 101.27 min. Plane C. Ascending node 181.6 degrees.
