No runway smoke. Not on a grass strip. Dust and grass maybe. I think the strip was about 4 500 feet and it was technically feasible to takeoff on as the takeoff run was about 4200 feet. Landing minimum was under 6 000 feet although 6 was the operating rule with a mandatory brakechute stream.
Mandatory that is unless there was a crosswind that prevented a stream. It was extraordinary but we never had in-limits crosswind landings on a 6 000 foot runway on a landaway. Can't think why.
Mind you the skipper streamed on the 11 000 foot strip at Goose and we couldn't understand that either. Especially as the whole ish dumped, in its valise, as soon as the drogue pulled the bag out of the stowage.
