On the 4th May 1941 , the prototype Mosquito's 100th flight-test achieved 392 mph at 22,000 ft. , weighing 16,000lbs.,[ faster than the then model Spitfire...] On 8 October with Merlin 77's [1710 hp.each,] a top speed of 439 mph was reached. The highest they flew were 43,600 ft. - Such were the first models, but the firepower, bomb weight [ a 4000 lb. ' Cookie' blast-bomb, ] rockets and mines, were superb for a two-man aircraft. - It didn't need torpedo's, with rockets and 20mm X 4 cannons, or .303 X 4 machine-guns to help aim the Molins 37mm or 57mm cannons [ 25 rounds in 20 secs, ] it punched holes in U-boats and ships, and it's remarkable wooden construction made them endurable and easily repairable. - The Mosquito was without doubt the most successful aircraft of WWII, nearly 8,000 were built of all variants and it's service extended until well after the War. - The Ju88 was a fine aircraft and an admirable opponent of the Mosquito, but it was heavier, not as powerful, not as well-armed and had more than 2 crew as a rule.
