Circumstances:
The crew was performing a training sortie from RAF Bovingdon. Enroute, the pilot encountered poor visibility due to foggy conditions and was unable to locate the destination airfield. Eventually, he ordered his crew to bail out and attempted to make a solo approach to RAF Bovingdon. Due to fog, he decided to reduce his altitude in an attempt to establish a visual contact with the ground when the airplane hit tree tops and crashed in Garston, east of the airfield. The pilot was killed while all five other crew members were later rescued.

Circumstances:
First prototype of the Hermes, this model H.P.68 (s/n 68/1) was later renamed H.P.81. Both crew members left Radlett Airfield to complete the first test flight on this new airplane. Few minutes after takeoff, while cruising in the vicinity of the aerodrome, the four engine aircraft went out of control and crashed in a field located 5 km from the airport. Both occupants were killed.
Probable cause:
Investigators considered that the accident was the direct result of elevator overbalance, this brought about flight conditions the nature of which caused the pilot to lose control. Although the porpoising motions set up by the overbalanced elevators would have been expected, the final manoeuvre of the aircraft, in climbing suddenly, cannot be satisfactorily explained. It seems certain, however, that at different trimmer settings, a reversal of stick forces would have occurred with which the pilot could not have kept in phase as the loads increased.

Circumstances:
The aircraft was on a local CFR flight circling the field at approximately 800 feet altitude with gear down. At a point in the traffic pattern 2 miles south of the field, and while turning downward, the B-17 collided with a C-47 (registered 43-48506) which had just taken off on local flight. The B-17 was slightly higher and behind the C-47 as it approached the C-47 from the port quarter astern. The B-17 was seen to make a sudden maneuver to avoid collision but too late to avoid the C-47. The C-47 was hit by the number 4 engine of the B-17 just forward of the tail fairing on the top of the fuselage resulting in complete loss of the tail empennage of the C-47. The C-47 then went into an uncontrolled spin and crashed about 2,5 miles south of the field, resulting in death of the two occupants. The tail unit came down in the same vicinity in a comparatively intact condition with vertical and horizontal control surfaces still in place. The left wing of the C-47 was severely crumpled by the impact. The B-17 was seen to make a violent maneuver to avoid collision but too late to avoid hitting the C-47. The B-17 then evidently stalled cut due to loss of flying speed resulting either from the maneuver to avoid collision or as a result of the impact, or a combination of both. The B-17 was seen to lower the left wing and then plunge straight down without spinning. It crashed into the ground at an estimated angle of 80° from horizontal. The collision occurred at an estimated height of 800 feet above the ground.
Crew in B-17:
Cpt Walter P. Hottenstein,
2nd Lt Joseph Cotterman,
Pvt James C. Shelton,
Pfc Eron J. Windham.
Probable cause:
The pilot of the B-17 evidently failed to observe the take-off of the C-47 or failed to keep it in sight while circling the field. The weather was good at the time except for moderate turbulence at low levels but with good visibility. Both planes were in the clear at all times. It seems probable that the C-47 was beneath the B-17 in such a position that it was in a blind spot. Local field regulations require that a left hand circuit of the field be made. An accident of this nature will serve to remind pilots of the constant necessity of observing traffic taking off as well as traffic already in the air. Pilots are being warned again to employ extra crew members as look-outs especially when in the vicinity of the airport.
