Alliance P.2 Seabird

The two-seater P2 Seabird biplane was designed in 1919 by J. A. Peters for the Atlantic competition, but failed to make an impact. Only two were built, distinguished by rear undercarriage radius rods on one, and front radius rods on the other.

The Alliance Aeroplane Company had license built aircraft in the First World War and afterwards decided to enter the civil market. The Daily Mail offered a 10,000 prize for the first trans Atlantic crossing and the designer J A Peters paid a 100 entry fee to the Royal Aero Club on the 17th April 1919. The plane (G-EAGL- lower picture) did not enter the race but did fly a trial flight from London to Madrid in record time of just under eight hours.
The second Seabird (G-EAOX) which suffered the fatal crash described by Vic Martin put an end to the Alliance company which was wound up in 1920.

I am interested in the aircraft and the Alliance Company. My father worked there during 1917-1919 and I have several photos of the plane with him as well. What I am most interested to see is if there are any drawings of the plans of the P2 as I would like to build a model. Please email me if you would like to swap information.
Regards David

Hi Vic Martin, there's a chapter on the incident in the book "Australia's Greatest Air Race" by Nelson Eustice (1969), re-published in 2008 by New Holland. I bought a copy last month from I can't now find it mentioned there, but you could email them. Cheers, Mike Nelmes, Australia.

The virtually identical Alliance Endeavour was an entrant in the England to Australia air race of 1919. The aircraft took off from Hounslow on the morning of 13th November 1919, but crashed a few miles away in an orchard near Surbiton Cemetery. Apparently the weather wasn't good, or there was a problem with the aircraft, because the aircraft was heading back towards Hounslow when it was seen spinning out of low cloud. Both pilots, Captain R.M. Douglas and Lieutenant J.L. Ross, were both killed in the accident.
Shortly before the record attempt, the aircraft had been badly damaged in a landing accident, requiring extensive repairs to be undertaken. The enquiry into the accident was irregular and some people thought that there was some kind of 'cover - up' by the Alliance Aircraft Company. They were however exonerated of all blame together with Napiers, whose 450hp Lion engine powered the aircraft. Does anyone have any more information regarding this fascinating subject? I've trawled around on the internet, but, so far have been unable to find any more information about the accident. I'd be really interested to learn more about what happened that day in 1919, just down the road from where I live.
Hoping you can help
Vic Martin
