My input often notes managerial/economic reasons that a pet project did not/could/should not have happened. That may seem like a declinist, negative stance. That's not where I am.
In 1935 Avro was
Ragwing City and the
rag was a Fokker wing licence. Then they did Lancaster.
Supermarine whittled wondrous wooden hulls. Then they did Spitfire.
Gloster was sold because their lean-to shed in a meadow had no work. Then they cascaded Hurricane and Typhoon.
et cetera.
From near-nothing we delivered
Heavies, by the hour, 1942-45.
And again, we delivered good
Heavies en masse, 1954-62. Here's a number:
Victor 1st.delivery 28/11/57 was 10 years+9 days from ITP: HP had 150 “engineers” in a payroll of 6,000; 5,500 Boeing “engineers” took 5 yrs. to 1st. B-47B (4/46-6/51), 9 (28/6/46 -29/6/55) 1st. B-52B. Not bad, HP. Even glorious.
Resources consumed, say in the nav/bombing system, could not do V-Bombers and more fighters, such as P.1083. We might call it a Hawker a/c. Tony Buttler would no doubt say HDA had a part to play. Undercarriage. et cetera. Coat..cut...priorities.
