96 tons of water!!!!! The hell with that, how about 400' AGL and only 140 KIAS? OK. I don't know where you saw 140 knots (I skimmed tie site, and didn't notice it). Numbers are for a -400, but -200 numbers should be similar: Call it 159 tons of airplane and 96 tons of water for ZFW of 255 tons. For a short cycle (2 hours airborne, plus reserve) try 35 tons of fuel, 1/3 of which has already been burned. GW at beginning of drop is about 280 tons. VREF for flaps 25 is 158 KIAS, so 170 KIAS is about the slowest I'd want to try. That is also the number given in a story in the Portland newspaper this morning. |

Seemed awful slow to me for a half million pound jet, but having never flown an aircraft with slats, I hear they're a wonderful device.

Speaking of the marketing vid , since when has the 747 ever took on a aerial refueling role? Wonder if they'll consider aquiring an old buff or a worn out C-5 as a water bomber aswell |

Cycle time between load and discharge and reload. To see a real water
bomber go to the Martin Mars Web site. Things are neat to watch. Talk about an overcast dropped just outside my town a couple years ago. Put out a 2 1/2 acre fire in about an hour. Dropped about 15 loads of water. Far more efficient than a 747. "Leadfoot" wrote in message news:Chpqc.69469$Fl5.45597@okepread04... http://tinyurl.com/2ejag 96 tons of water!!!!! |

Dropped about 15 loads of water. Far more efficient than a 747. But keep mind, not even considering the 747, dropping retardant and dropping water are two different operations with two different purposes. Water is put directly on a fire, retardant is typically put in the fires path to make a line... Ron Tanker 65, C-54E (DC-4) Silver City Tanker Base |

Oh and BUFDRVR, you might note of interest that the USFS aviation officer who
is determined to kill of the airtanker program, is an ex-Bone driver Guess we should have heeded your words about them earlier Ron Tanker 65, C-54E (DC-4) Silver City Tanker Base |
