Squadron Operations: Summary Information

Overview

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:

• 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: Ulm (17 Dec 1944 - 18 Dec 1944)

Operation Summary
Target	Out	Back	Aborted (Y / N)	Comments
Ulm	17 Dec 1944	18 Dec 1944	N	29 crews were briefed to attack the rail junction at ULM situated some 100 miles inside the German frontier on the banks of the Danube. Heavy cloud compelled low flying for most of the way, but in the target area there was little more than thin stratus which did not prevent ground markers from being seen through it. The Master Bomber' assessment of the situation however was that the best results were likely to be produced from aiming on the well placed and plentiful sky markers and ordered bombing accordingly. A very good concentration of fire developed, with a number of spectacular explosions occuring among them. Defences were meagre and there were no searchlights active. S/L Caldow "B" was unlucky - one of the few flak bursts over the target hit one of his aircrafts fuel tanks, which promptly emptied, the tailplane, elevators damaged and one of the aerials shot away which did not interfere with a safe return and landing at Base. No flying training was carried out.
