550 Squadron and RAF North Killingholme Association

Squadron Operations: Summary Information

Overview

There follows below a list of the all of the operations flown by 550 Squadron and the aircraft involved on each. The information used to build this page was taken in the first instance from the lists provided on the original Squadron Association web-site, but has been augmented by new information gathered since that time (squadron operations logs, individual aircrew log books, and other sources).

This information is not yet complete: it has been build from the a number of sources (documentary and people) and compilation of complete lists is an ongoing task that is expected to take quite some time to complete. So please don't shout just yet if you spot an omission - work continues to build a more complete, and accurate, list.
Do however shout if you spot an error! Please email any corrections or information to the contact details in the link at the bottom of the page.

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

the operation was cancelled before crews were briefed
the crews have been briefed as to the target, and in some cases the planes may even have been bombed up and the crews on-board at their stations awaiting take-off, before the op has been stood-down
finally a number of cases where the op was already under way and the planes en-route but for whatever reason the operation was aborted (e.g. the master bomber orders the attack cancelled due to weather conditions at target adversely affecting targeting).

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: Heligoland (18 Apr 1945 - 18 Apr 1945)

Operation Summary
Target	Out	Back	Aborted (Y / N)	Comments
Heligoland	18 Apr 1945	18 Apr 1945	N	28 aircraft with crews took off in the usual 550 Squadron style at 10.10hrs to attack the German fortified island of HELIGOLAND. The crews were delighted at being able to participate in another daylight raid. The journey outward was uneventful and visibiity was excellent, the weather being that of a hot summer's day. Our contribution was part of a force of 950 aircraft. Bombing commenced a minute early and the absence of marking in no way affected the accuracy of the bombing. Indeed, the concentration of bombing was so tremendous that it was not thought that markers, had they been dropped, would have remained visible long enough for them to have been used as an aiming point. The island was so saturated by the weight of the attack that the crews met only negigible opposition from the ground defences. No enemy aircraft were encountered. A great number of excellent photographs were obtained giving proof of an outstanding attack. An aircraft carrying a movie-camera was present throughout the attack. P/O Town had to return early owing to engine failure. Eleven hours night flying training was also carried out.

Station Summary
OPERATIONS: A daylight operation took place on the defensive fortress of HELIGOLAND ISLAND. 28 aircraft took off from North Killingholme, one was abortive due to excessive coolant temperature in the port outer engine, and the remainder bombed the primary with excellent results.

Note

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.
