If I recall correctly, the Typhoon escort was RAF 198 Sqn. and because of the bad weather didn't connect so were not able to escort - The nearby Luftwaffe were alerted to the Amiens prison attack and II/JG 26's Fw-190's chased & attacked the stragglers which unfortunately shot down the 140 Wing's raid leader, Grp. Capt. Percy Picard & his nav, Flt. Lt.'Pete' Broadlley - Some will remember Percy Picard from his role as the pilot in the famous "Target for Tonight" wartime movie...
In regard to Crimea_River's statement that the first built was in Canada is indeed correct, but I believe all the new wood fuselage was the first-off Glyn Powell's moulds from his factory here in NZ...
-The last flying Mosquito RR299 crashed at Barton Aerodrome in UK on 21 July 1996 killing both crew, Steve Watson & Kevin Moorhouse- A huge human tragedy, & unfortunately, a loss as RR299 was also a 30+ years UK Airshow circuit favourite - It was a T.III dual-control trainer based on the FB.VI...- Glyn Powell's one is an Aussie-built T.43, a version of the T.III - At the time of the 1996 crash there were around 31 surviving Mosquitoes worldwide. It really is marvelous that Kermit Week's and others are now able to gradually return these awesome aircraft to the skies and airshows for all to see, the sound of those two Merlins...wow... and such a huge testament to the talents of ALL those involved in Warbird Restoration, worldwide...
Cheers
