If "bounced" while cruising at low speeds it could take a Spitfire up to two minutes to accelerate to top speed. [58] The only way it was thought that a Spitfire could evade attack was to cruise at high speed and go into a shallow dive with the throttle open. Provided the Fw 190 was seen in time, it could be forced into a long stern chase. [57]
Different wings, featuring a variety of weapons, were fitted to most marks; the A wing used eight .303 in (7.7 mm) machine guns, the B wing had four .303 in (7.7 mm) machine guns and two 20 mm (.79 in) Hispano cannons, and the C, or universal, wing could mount either four 20 mm (.79 in) cannons or two 20 mm (.79 in) and four .303 in (7.7 mm ...
The lamprey fell off after less than 6 meters, so the railway was determined to be effective at preventing the sea lamprey's migration. In 1976, it was finally decided that a new, enlarged railway would be built. The current carriage was opened to the public in 1978, and can carry a boat up to 100 feet (30.48 m) long and 24 feet (7.32 m) beam. [1]
The matter of a seaborne Spitfire was raised again in November 1939 when the Air Ministry allowed a Commander Ermen to fly a Spitfire I. After his first flight in R6718 , Ermen soon learned that Joseph Smith , Chief Designer at Supermarine, had been instructed to fit an "A-frame" arrestor hook on a Spitfire and that this had flown on 16 October ...
The use of these prefixes did not change according to the wings, which could be fitted with "clipped" tips, reducing the wingspan to about 32 ft 6 in (9.9 m) (this could vary slightly), or the "pointed" tips which increased the wingspan to 40 ft 2 in (12.29 m). Spitfire F Mk XIIs of 41 Sqn.
Spitfire PR Mk XIs were capable of a top speed of 417 mph (671 km/h) at 24,000 ft (7,300 m) and could cruise at 395 mph (636 km/h) at 32,000 ft (9,800 m). Normally Spitfire XIs cruised between these altitudes although, in an emergency, the aircraft could climb to 44,000 ft (13,000 m) However, pilots could not withstand such altitudes for long ...
Other changes to the airframe included flush rivets externally, and shortened and more rounded wing tips which reduced the span from 36 feet 10 inches (11.23 m) to 33 feet 8 inches (10.26 m). Internally, the gun mountings were omitted and all military equipment, including the weapons and radio fits, was removed.
A schedule of ship's boats of 1886 shows 34 to 30 feet (10.4 to 9.1 m) cutters pulling 12 oars, 28 feet (8.5 m), 10 oars, 26 to 20 feet (7.9 to 6.1 m), 8 oars and the two smallest sizes of 18 and 16 feet (5.5 and 4.9 m), 6 oars. The smaller boats could be single banked whilst the larger and later examples were generally double-banked. For ...
