Wow,
10,000 gallons of water.....even using the smaller US gallon that equates to about 83,450 lbs!! (Could it have read liters??).
Quite some Bambi Bucket!!
The largest load for a Skycrane is 2650 USG which weighs in at about 22114 lbs give or take.
Not overly familiar with the fixed wing types like the CL215T and CL415 but I would still think their tank inlets are pretty small (when trying to extrude a diver through!!).
The Bombardier web site says the 415 can carry 1621 gallons (approx 13500 lbs) so give me a Skycrane any day!!
