Squadron Operations: Summary Information


Listed below is the information available for operations to this target flown by 550 Squadron.

Operation Summary: The column headers should be fairly self-explanatory. The term "aborted" as used here covers a number of possibilities:

Aircraft Deployed: When a link to a particular aircraft is given, this indicates aircraft known to have taken part in this raid (in the records currently available to the web-site author). A record of whether the aircraft returned or failed to return (FTR) is also logged.

Servicemen Deployed: Names of the crew in the operation.

Station Summary: This section is the information from the RAF North Killingholme Station Record Book for the operational date (if available).

Definitions of the abbreviations used are available: here.

Manageable Lists

The amount of data in the database is growing and this is resulting in the "all operations/targets" list getting rapidly bigger and thus slower to generate. There are options to display shorter, more quickly generated, reports if you want to home in on something specific. For example, there are options to generate reports on operations to a single target, or by single aircraft (to all targets) or by single aircraft to a single target. There is, on the database-reports summary page, a short user guide (PDF format) on how to do this.

Operation/Target: Herne Oil Plant (13 Mar 1945 - 14 Mar 1945)

Operation Summary

(Y / N)
Herne Oil Plant 13 Mar 1945 14 Mar 1945 N The Squadron was required to provide 12 aircraft for a night attack on the Erin Benzole Plant at HERNE which is in the north central area of the Ruhr close to the Rhine-Herne canal. All 12 aircraft took off neatly and without incident at approx. 17.15 hrs. Patches of 4/10 Stratocumulus cloud with tops at 12000 ft were encountered all along the outward route over this country. After leaving the English coast the route was cloudless until reaching the Rhine were more stratocumulous formed and rapidly increased to 9/10 in the target area with tops 10/12000 ft. There was a considerable [amount] of haze over the whole route. Only ground markers were provided and these were obscured to a considerable extent by haze and cloud. As a result, a large number of crews had to bomb on navigational aids and whilst a fair concentration of bombing was achieved on the ground markers, there was a considerable amount of undershooting and overshooting and probably half the effort was wide of the target area. An encouragingly large explosion was reported in the target area; however, something must have gome up. Only moderate heavy flak was encountered over the target and searchlight illumination was not attempted. Jet aircraft were active over the target area but none of our aircraft were molested. All our aircraft landed safely at base and there was quite a series of celebrationbs as the following captains, F/O Summons, F/O Ferguson and F/L Rhude, had with their crews, all completed their tours.

this list is still being built and will take some time to complete
what is currently displayed is believed accurate but much more is still to be added

This note describes the options currently available to produce a smaller, more manageable list and also describes planned future enhancements to the reporting facility.
