Initial Response to STS 51-L Mishap

The following is a chronology of the actions taken and events logged by the Department of Defense Manager for Space Transportation System Contingency Support Operations (DDMS), Support Operations Center (SOC), Booster Recovery Forces, and the Landing Recovery Director (LRD) following the structural breakup of STS 51-L at 1139 hours Eastern Standard Time (EST) on January 28, 1986, until termination of the surface search effort on February 7, 1986.

 

28 January 1986

1140 EST

Personnel on board the SRB recovery ships did not observe the structural breakup due to cloud cover in their area. The Liberty Star and Freedom Star were notified by the LRD via the Booster Recovery Director (BRD) of the accident and were given the approximate latitude and longitude of the impact area. The two ships pro-ceeded immediately at best speed (15 knots) toward the impact point. The recovery ships pick-ed up several pieces of debris while en route to the impact area.

The first H-3 helicopter (call sign Jolly 1) was notified to take off and hold short of the safety zone established for falling debris.

1141 EST

Aircraft and ship search and rescue support was requested by the SOC using the search and rescue telephone network (SARTEL).

1142 EST

The National Military Command Center (NMCC) was notified by the SOC of the mishap and a continuous dialog was established.

1146 EST

The SOC requested Range Safety Office (RSO) provide an estimated time of when the debris impact area would be clear to allow rescue forces to enter. Estimate was 55 minutes. Periodic updates were requested.

1150 EST

Jolly I reported sighting debris falling and impacting the ocean surface.

1210 EST

An HC-130 aircraft and two HH-3 helicopters departed the Clearwater Coast Guard Station for the mishap area.

1214 EST

The Joints Chiefs of Staff (JCS) formed a Shuttle Response Cell. A briefing was provided by SOC personnel.

1230 EST

The second H-3 (Jolly 2) reported being airborne and proceeding to the area.

1231 EST

The JCS Shuttle Response Cell was provided an update by SOC personnel.

1237 EST

The RSO cleared SAR aircraft (three fixed wing, three helicopters) into the safety zone. Aircraft reported sighting debris even before entering the area.

1250 EST

All Department of Defense (DOD) forces not supporting the SAR activities were released.

1259 EST

The SOC provided an update of the current situation for the Chief of Staff, Air Force.

[O152]

1311 EST

Miami Rescue Coordination Center was assigned responsibility of SAR mission coordinator for the SAR operations by Coast Guard COMLANTAREA.They requested the Eastern Space and Missile Center Aircraft Control Officer (ESMC/ACO) control SAR aircraft in the area for them.

1315 EST

The SRB Marine Operations Manager (MOM) had laid out the search pattern and directed the vessels in conducting the search. Hard contacts were identified via sonar on the bottom and their positions plotted. Both Liberty Star and Freedom Star launched their Avons to recover floating debris while the sonar search continued.

1356 EST

Three Coast Guard cutters (CGC) reported en route to the area.

1400 EST

Initial debris handling procedures were established. Explosive Ordinance Disposal (EOD) personnel were placed on standby.

1624 EST

The NASA Landing Recovery Director (LRD) requested DDMS to initiate a major SAR effort when it became apparent that local resources would not be adequate.

1650 EST

DDMS alerted the Navy Supervisor of salvage and requested a representative deploy to Cape Canaveral AFS.

1715 EST

SAR aircrews were debriefed. Copies of logs, charts, and written statements were provided to NASA/EX-NAMO.

1730 EST

BRD contacted Perry Offshore regarding availability of the Remotely Operating Vehicle (ROV), SPRINT. The BRD also contacted SONAT in Houston, Texas to obtain the services of the ROV, SCORPIO. MOM directed Freedom Star to continue the search and Liberty Star to proceed to port.

1800 EST

Twelve aircraft from Air Force, Navy, and Coast Guard were participating in the search. In addition, ten Navy, NASA and Coast Guard ships were in the search area.

2030 EST

Liberty Star and Freedom Star arrived in port to off- load retrieved debris.

2100 EST

ROM directed by KSC Deputy Center Director to call up whatever support necessary for mobilization.
