We will be visiting the South Rim in mid-May.
We are considering taking the 45 minute flight on their twin turboprop airplane. I know there is much debate about this but I believe their planes are much quieter than any commercial helicopter. They apparently changed the prop from a 3-bland to a 4-blade to make that quieter.
Think the helicopters might still go below the rim of the canyon but this isn't an issue for us as we will be doing the overnight mule ride down to the river.
I think this trip may cover more area than the helicopters -- out to the east, over the North Rim/plateau, and then back. Also I believe the helicopters have tinted glass so that makes picture taking more difficult. This plane has large, clear windows (and air conditioning).
I was thinking of reserving for a 3 PM flight as there will be more shadows that might make the view better than mid-day but the sun will be still fairly high in the sky since the sun sets at about 7:25 then.
Any suggestions, please.
