closely to verify that the chute was equipped with a slider.Â* Note
that the jumper had a 25 second ride after full deployment.

Mine's a Strong 303 (26' conical; back). Comfy with sheepskin. Here's a video of a model 304 (26" conical; chair) in action with the same canopy I believe. 2011 bailout from a disabled Mustang. Legend states bailout was less than 500', but with what seems a delay in pilot-chute deployment yields a very quick, low-altitude loss safe. Make your own calculations. Isn't the speed and direction of travel at deployment key factors (e.g., Jumping from vertical @ 0 mph results in greater alt loss than at 45 degrees @ 100 mph)?

The old Irvin EB80 was reckoned to be life saving from 100ft with 100kts horizontal speed. There was a VTC Open Cirrus that fluttered apart on a high speed pass in the UK many years ago and the pilot bailed and survived with one. I tried to buy one new but there was a 6 months waiting list, so settled for a very comfortable GQ Silhouette which was lifed at 15 years;^(. Replaced it with a Butler, which is fine.

I must appologise for bringing up square chutes, as the thread has gone off the tracks as usual. This was supposed to be about comfort. They are not mutually exclusive, but separate considerations.
