Paul Allonby, the author of the book COURAGE ABOVE THE CLOUDS:

TIMELINE FEBRUARY 22ND 1944 – MISSION 230 – AALBORG DIVERSIONARY RAID

23.15 21.02.44 MAXIMUM EFFORT orders forwarded to 305th Bombardment Group at Chelveston and the 92nd BG at Podington.
Groundcrews briefed on fuelling and payload. Work commences at dispersal points at both airfields to ready the maximum number of B-17s possible.

01.15 22.02.44 ORDERS arrive via teleprinter from FIRST BOMBARDMENT DIVISION HQ at Brampton Grange for specialist staff at Chelveston and
Podington to begin preparing briefings for air-crew.

03.15 AIR raid sirens sounded at both bases – Luftwaffe bombers detected operating in the area. Work continues to prepare the aircraft for the raid.

04.00 CREWS destined to fly on the mission are woken.

04.31 ALL-CLEAR. Air raid siren sounded to signify Luftwaffe bombers have now left the area.

05.00 CREWS at both bases are briefed on the forthcoming mission, which is intended to divert Luftwaffe fighters from heading southwards to intercept 
the main mission – which is targeting aviation manufacturers and German bases within Germany. (See also The Big Week)

08.00 AIRCRAFT begin taking off from Chelveston and Podington. The main force heading to Germany departs an hour later.

09.06 THE amalgamated formation, with the 92nd BG leading, gathers then finally departs from its rendezvous point above Louth in Lincolnshire, heading
on a dog-leg course over the North Sea for Denmark.

13.01 LUFTWAFFE fighters are scrambled to meet the formation of B17s, tracked heading towards Denmark. They are on a route which could see
them attack targets in Denmark, or head towards Hamburg or other German cities.

13.08 THE B17s sight the Danish coast – but the country is covered in solid cloud, with the cloud topping out at 8,000 feet. The formation is flying
at 24,000-feet.

13.25 ENEMY fighters encountered for the first time over the Danish coast. The interceptors are deterred from pressing home their attack by strong
defensive fire from the B17s. The bombers are also fired upon by anti-aircraft guns.

13.38 GERMAN pilots confirm to ground control that not only is the mission, given the number of aircraft, a diversion but reveal that some of the aircraft
are the new ‘’G’’ variant of the B17 with a chin turret for additional defence.

13.55 LUFTWAFFE ace Hans Müller is vectored to the American formation. Flying a JU-88, he is told to observe the bomber formation, particularly
regarding the defensive capability and effectiveness of the B17g participants in combating head-on attacks from Luftwaffe Me109 defending fighters.

14.13 THE bomber formation arrives at Aalborg (here - zoom), but visual bombing is not possible. The crews circle the city, twice. Radio messages
are exchanged between lead crews over what to do. A decision is made to follow the briefing recommendation to drop the bombs safely over the sea,
as no secondary target has been highlighted.

14.26 LUFTWAFFE fighters, though limited in number, began attacking the B17s with vigour, with further anti-aircraft fire at 14.43

14.42 HANS Müller attacks, and shoots down, ‘HOT ROCK’. The aircraft is last seen heading out to sea heading in the direction of Sweden, but
appears out of control. At one stage a crewman bales out but his parachute snags on the badly damaged aircraft. Lt Muller could only look on in horror
as efforts are made by men on the aircraft to retrieve their colleague, with Lt. Muller radioing its position as it disappears into the cloud. In this encounter,
a Me109 Luftwaffe fighter, flown by Kurt Schwarz disappears. His body is later recovered from the sea. No trace is found of the B17 crew.

14.45 WITHIN minutes, Lt. Müller engages ‘POT O’GOLD’ causing severe damage.  He takes a position behind and to one side of the stricken bomber
so the crew can bale out, before the aircraft crashes down onto Danish farmland.

14.55 – 15.20 ALL bombs carried by the B17s are jettisoned into the North Sea.

15.00 DEFENDING fighters again engage the American bombers, with Herbert Christmann claiming ‘’ace’’ status with the downing of ‘’LIBERTY RUN’’ –
the fifth enemy aircraft downed to date in his career - which crashes into the North Sea, nine crew being seen to bale out. Squadron Leader Christmann
radios the downed aircraft’s position, so air-sea rescue assets can be launched, but no survivors are found despite an intensive search.

15.02 ERICH Naujokat, flying his first interception mission and operating as wingman to Herbert Christmann, engages ‘MI-AMIGO’ in what his colleagues
described as a ‘’spirited’’ attack, with strikes being seen on the bomber’s wings and fuselage. He in turn is met with defensive fire from the B-17,
particularly from the rear and waist gun positions, and his aircraft is seen to dive into the clouds, out of control. Again, despite a search, no trace of him
is found until his body is eventually recovered from a beach in Sweden.

15.10 THE Luftwaffe fighters begin heading back to base as the B17s head towards home across the North Sea, now travelling at 19,000-feet.

15.15 ‘MI-AMIGO’ – trailing smoke from her wings and at least one engine – begins lagging behind the formation and eventually is lost from sight.

16.10 RADIO transmission from ‘MI-AMIGO’  using call-sign LIFTBOY VICTOR is received and answered. The badly damaged bomber is still airborne,
and wants a vector to RAF emergency landing grounds in Yorkshire.

16.28 THE B17s travelling ahead of ‘MI-AMIGO’ make landfall over the English coast only to find heavy cloud blanketing much of central England.
Permission is granted for the incoming bombers to land at other airfields if necessary due to the weather conditions.

16.53 AIRCRAFT begin landing at Chelveston and Podington.

16.59 ‘MI-AMIGO’ emerges from low cloud over Sheffield, South Yorkshire, with engines faltering.

17.02 NO survivors as ‘MI-AMIGO’ crashes into Endcliffe Park. See also Sheffield Bomber Crash: Flypast on 75th Anniversary.
