Re: North American F-100 Super Sabre
These findings were subsequently confirmed during Project Hot Rod operational suitability tests. Particularly troubling was the yaw instability in certain regimes of flight which produced [Vous devez être inscrit et connecté pour voir ce lien].
The aircraft could develop a sudden yaw and roll which would happen too fast for the pilot to correct and would quickly overstress the aircraft structure to disintegration.
It was under these conditions that North American's chief test pilot, [Vous devez être inscrit et connecté pour voir ce lien], was killed while dive testing an early-production F-100A on 12 October 1954.

Another control problem stemmed from handling characteristics of the [Vous devez être inscrit et connecté pour voir ce lien] at high [Vous devez être inscrit et connecté pour voir ce lien].
As the aircraft approached [Vous devez être inscrit et connecté pour voir ce lien] speeds, loss of lift on the tips of the wings caused a violent [Vous devez être inscrit et connecté pour voir ce lien].
This particular phenomenon (which could easily be [Vous devez être inscrit et connecté pour voir ce lien] at low altitude where there was insufficient time to recover) became known as the "[Vous devez être inscrit et connecté pour voir ce lien]".

Nevertheless, delays in the [Vous devez être inscrit et connecté pour voir ce lien] program pushed the [Vous devez être inscrit et connecté pour voir ce lien] to order the raw F-100A into service.
TAC also requested that future F-100s should be fighter-bombers, with the capability of delivering [Vous devez être inscrit et connecté pour voir ce lien].

Operational history
The F-100A officially entered USAF service on 27 September 1954 with [Vous devez être inscrit et connecté pour voir ce lien] at [Vous devez être inscrit et connecté pour voir ce lien], CA. By 10 November 1954, the F-100As suffered six major accidents due to flight instability, structural failures, and hydraulic system failures, prompting the Air Force to ground the entire fleet until February 1955.
The 479th finally became operational in September 1955.

Re: North American F-100 Super Sabre
Due to ongoing problems, the Air Force began phasing out the F-100A in 1958, with the last aircraft leaving active duty in 1961.
By that time, 47 aircraft were lost in major accidents.
Escalating tension due to construction of the [Vous devez être inscrit et connecté pour voir ce lien] in August 1961 forced the USAF to recall the F-100As into active service in early 1962.
The aircraft was finally retired in 1970.

The TAC request for a fighter-bomber was addressed with the F-100C which flew in March 1954 and entered service on 14 July 1955 with the [Vous devez être inscrit et connecté pour voir ce lien], [Vous devez être inscrit et connecté pour voir ce lien], TX.
Operational testing in 1955 revealed that the F-100C was at best an interim solution, sharing all the vices of the F-100A.

The uprated J57-P-21 engine boosted performance but continued to suffer from [Vous devez être inscrit et connecté pour voir ce lien].
On a positive note, the F-100C was considered an excellent platform for nuclear [Vous devez être inscrit et connecté pour voir ce lien] because of its high top speed.
The inertia coupling problem was more or less addressed with installation of a yaw damper in the 146th F-100C, later retrofitted to earlier aircraft.
A pitch damper was added starting with the 301st F-100C, at a cost of US$10,000 per aircraft.

Re: North American F-100 Super Sabre
The addition of "wet" hardpoints meant the F-100C could carry a pair of 275 US gal (1,040 l) and a pair of 200 US gal (770 l) drop tanks.
However, the combination caused loss of directional stability at high speeds and the four tanks were soon replaced by a pair of 450 US gal (1,730 l) drop tanks.

Re: North American F-100 Super Sabre
The 450s proved scarce and expensive and were often replaced by smaller 335 US gal (1,290 l) tanks.
Most troubling to TAC was the fact, that, as of 1965, only 125 F-100Cs were capable of utilizing all non-nuclear
weapons in the Air Force inventory, particularly [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien] air-to-air missiles.[Vous devez être inscrit et connecté pour voir ce lien]
By the time the F-100C was phased out in June 1970, 85 had been lost in major accidents.

Re: North American F-100 Super Sabre
The definitive F-100D aimed to address the offensive shortcomings of the F-100C by being primarily a ground attack aircraft with secondary fighter capability.
To this effect, the aircraft was fitted with autopilot, upgraded avionics, and, starting with the 184th production aircraft, the Sidewinder capability.
