Dr. James was injured as a result of the crash.
24th May 1953 Dr. James had made some adjustments to the carburettor in anticipation of the forthcoming Kings Cup air race for which he would have been a competitor. Unfortunately these adjustments appeared to be instrumental in causing the engine to fail as he came up to Felixstowe to over-fly his daughters' school. Dr. James managed to glide over the town to Trimley and was lined up to make a landing in a field when people appeared walking across his intended line on a previously unseen foot path, he tried to stretch the glide to make the next field but hit the top of the far hedge.
24th June 1984 Restored to register – Roy Nerou, Coventry.
14th Sept. 2001 First post restoration flight, flown by Roger Bailey from Rendcomb private aerodrome. The Chilton flew beautifully with no problems and returned effectively brochure figures of 60 years earlier. This is the first time a Carden engined Chilton has flown in almost fifty years and confirmed the heavy Carden Ford engine of only 30hp is quite capable of giving a creditable performance in this lightly built airframe.

3rd July 2005 Old Warden, Summer Air Day and Air Race, the Chilton was in the lead but was over taken in the last second by the Martlet, we were robbed!! Well raced by Rob Millinship.
The Chilton almost across the line when the Martlet just nosed ahead.
30th July 2005 Leicester - Rendcomb, did a very accurate fuel consumption check, it works out that the Carden is doing 9.2 Lts/Hr. at 3,100 rpm, Rob flying.
5th June 2006 All the previous 47 hours flying has been carried out using a 50.5”x 26” propeller, having received authorisation from the PFA, the aircraft was fitted with a 48”x 30” prop, this being a copy of a broken original Chilton prop. Comparative tests carried out give the following results:- 50.5”x 26” propeller – time to climb 1000’ – 2000’ 1 mins 30 secs. New 48”x 30” prop, time to climb 1000’– 2000’ 1 min 59 sec, both tests carried out within 45mins of each other at +24°C. Top speed with new prop is increased by approximately 10mph to 110mph @ 3,500 rpm.
16th June 2006 The Chilton was demonstrated for The Hon. Colin Dalrymple and Hon. Mrs. C.J. Dalrymple, John Dodd doing the flying. Colin last saw his elder brother Andrew fly the Chilton before the war.
2nd July 2006 Old Warden, Shuttleworth Summer Air Display with 1930’s style air race, it was very very hot, it was so hot that the water temp gauge was reading 40 deg. before we started the engine. A potential problem due to the prolonged taxiing and waiting to start, as the first man off was the Hawker Cygnet that I think had to do a complete lap before we went off but the temp went up to 70 deg on the ground then stabilised. If I had used the original old brass rad she would have boiled for sure. We were handicapped second from last with the Comper Swift as scratch man, but the Chilton was handicapped out of contention as the Swift went off only about 20 secs later and of course it's much faster aircraft, so passed 'ESZ on the last lap even though Rob didn't hold back!
15th July 2006 Old Warden, Shuttleworth Evening Air Display. Rob displayed it in company with the Comper Swift, Turbi & Martlet
16th July 2006 Breighton Summer Air Display, (Old Warden to Breighton 120 miles used 12 Ltrs fuel) Rob displayed it in company with Aeronca 100 G-AEVS (I used to own), Arrow Active, Miles Magister & DH Chipmunk. Total flight time since rebuild 56 hours with 80 separate flights.
20th August 2006 Popular Flying Association Rally at Kemble, flown in by John Dodd.
27th August 2006 Wing and Wheels Display at Dunsfold the old Hawker airfield about 25 miles south of London, sadly soon to disappear under houses, flown via White Waltham by John Dodd.
10th Sept. 2006 Rendcomb, demonstration flights at Jan Cooper's informal fly-in held in memory of Ben Cooper, flown by Roger Bailey and by Nigel Reid whilst I took some air to air shots from Jan's Fox Moth G-ACEJ.
1st July 2007 Flown to Old Warden for the Summer Air Day, sadly the show was cancelled due to a water logged runway, the Chilton was got out on the day but very high winds prevented it flying.
14th July 2007 Old Warden, Evening Air Display, Rob Millinship put up a sprited display on a perfect evening.
10th Sept. 2007 Leicester, air to air photos from Taylorcraft G-BRPX. First communication using old RAF flying helmet with modern ear pieces and oxygen mask with mic and ICOM hand held radio, not perfect, but useable even with background magneto noise because of unscreened ignition.
Her 1938 racing number is applied on 3 May 2008.
4th May 2008 Rendcomb, first flight with her reinstated 1938 racing number, flown by Roy Nerou, strangely she didn't go any faster with her racing number on!
19th July 2008 Old Warden, Evening Air Display, Rob Millinship did well in very high winds.
16th August 2008 Old Warden, Evening Air Display, the Chilton was wheeled out but along with all the other lighter types could not fly as winds gusting up to 30kts.
23rd August 2008 Sywell, (Northampton) Rag-Wing Fly-in, flew out from Old Warden in company with a Ryan PT22, Focke-Wulf Stieglitz, Bucker Bestmann, and a Klemm KL35, we all cruised at approx 90 mph at which speed the Carden was turning over at 3,200 rpm. Then from Sywell back to Rendcomb, because of low cloud obscuring the sun it was possible to read the compass down under the panel between my knees, in sunny conditions after staring into the bright sky then averting ones eyes down below the panel into apparent dark makes reading or seeing the compass problematic.
11th Sept. 2008 Folly Farm, Hungerford, less than a mile from Chilton House where the Chilton was built. John Dodd flew the Chilton as part of a private display in front of invited guests in aid of the Soldiers, Sailors, Airmen & families Association charity.
