I am sorry to see that the topic on the Corsair accident has been closed(locked) on WIX. I believe there are usually things to learn from the analysis and discussion of an accident.
The first point I'd like to make is the safest procedure or at least safer procedure is when taking off in a group of tailwheel planes like fighters or T-6s, Wait Until The Previous Plane Has FULLY LIFTED OFF Before Starting To Roll. DON'T Go When Just The Tailwheel Is Up.
This method, that of seeing the plane before you fully lift off the runway before starting down the runway is the safer way, and it is this way that I was taught 25 years ago when I came into warbirds. Howard and other CAF pilots were mainly the people who showed me the procedures.
One change that occurred over the years, was the growth of large formation groups like T-34, T-28, T-6, and some of the emphasis changed from safety with patience to trying to rush large number of planes off quickly. You can do a lot in a T-34 that has fabulous vision over the nose, fairly low power and a stall speed of 48 knots VSO. A fighter is not the same thing.
I would add my voice to Bill's on this.
Tailwheel fighters are basically blind in an angular cone extending (depending on type of course) about 20 to 25 degrees on either side of the windshield with the pilot's head as the apex of this equilateral triangle.
Section and most assuredly flight take offs can be extremely dangerous in these airplanes during the period defining power up by the wingmen and when the noses of the wingmen come down.
There are several areas of danger associated with formation takeoffs in tailwheel fighters. Visual cue as stated is of course of primary concern.
As well, there is the insidious and seldom mentioned factor involved with being a number 2 or deeper in a section or flight takeoff that involves the psychological urge and natural instinct for the wing position pilots beginning the roll to FORCE DOWN the noses of their aircraft earlier than they would ordinarily to regain visual cue on the aircraft obliquely in front of them.
If this occurs, and if often does in these situations, it places the aircraft in the worst possible condition for both yaw and roll excursion as torque acts on the aircraft in ROLL, the downward movement of the prop disk in pitch causes precession, and P Factor is rising on the prop until the nose reaches coincidence with the relative wind.
Formation takeoffs in tailwheel fighters are a subject that should be getting MUCH more attention than it has in the past.
