    Default Meteorological Observations and Forecast March 5-6, 1945

    On the late afternoon of March 5, 1945 severe local weather conditions in the vicinity of Tholthorpe and Linton resulted in the loss of 7 aircraft and 40 aircrew killed and 9 survivors.

    From the M.O. Form 2373, March 1-31, 1945 Daily weather report.

    March 5, 1945 General Inference: A large anticyclone is centred West of Ireland and a small depression off North Scotland is moving SSE. Weather will cloudy with local rain at first, but some bright intervals are likely later except in the N.W. It will be rather cold.
    Weather observations:
    Barometric Pressure at Leeming.
    March 5:
    Time Pressure
    00:00 33.3 m.b.
    06:00 31.6
    12:00 29.6
    18:00 28.8
    March 6
    00:00 29.8
    06:00 29.4

    Outcome:

    Severe Conditions Over Northern England and Crashes

    Dad recalled "The weather was punk. It was rotten!" F/Lt. Geoff Marlow 434 Squadron remembered “…moments after take-off, we entered stratus cloud, and I began flying on instruments. We tried to climb above the clouds, but the heavily laden Lancaster simply would not go any higher. During one of these attempts I took my eyes off the instruments for a few moments, and when I looked at them again, they told me that we were losing height at 1,000 feet-per-minute and were in a 45o bank. As I got the plane under control and back on course, I felt a little embarrassed, but when I looked around at Frank Ferry sitting next to me, he seemed not to have noticed anything unusual, so I kept quiet, and set about trying to regain the lost altitude!”

    On the outward route over Yorkshire, aircraft from the stations at Tholthorpe and Linton were severely affected by severe local weather cells which caused severe icing beginning at 2,000’ . 426 Squadron (Linton) lost 3 aircraft: S/L Garret (7 killed), F/O Watts (7 killed) and F/L Emerson (6 killed+1 survivor) . 420 Squadron (Tholthorpe) lost 2 aircraft: P/O Sollie (6 killed+1 survivor) and P/O Clark (4 killed+3 survivors) . 425 (Tholthorpe) lost 2 aircraft: F/O Lowe (4 killed+3 survivors) and P/O Anderson (6 killed+1 survivor) . Take-off times for these aircraft were 1628-1648 hours. There were 9 survivors from these crashes and 40 crewmen were killed . Upon return to England, F/O. Reitlo and all of his crew were killed, and a Court of Inquiry concluded icing was believed to be a contributing factor.

    Further to this there was general criticism of the meteorological section on the expected weather over the return route over the French Coast:

    The 419 Squadron ORB records F/O Peter Tulk reported that the force should have returned over England at 8,000’ and F/Lt. Fred Dawson stated that the icing at the French coast was too high for briefing heights . S/L Dave Hunter offered the sarcastic and damming inditement that “route and tactics good if Met had been right! ” Dad opined that coming out from French Coast, briefed heights too low for icing conditions. The route called for heights of 5,000' descending to 2,500' at the French Coast. The navigation log for F/O Seale records Dad flew at 15,000'.

    A total of 88 aircrew from 6-Group were killed either in crashes or in combat over Germany. A further 17 Canadians serving with other units were killed on the operation to Chemnitz .

    I would appreciate any comment from the "Met Gen Men" on this forum on this event.
