thanks for ruining a cute and funny LOUNGE story which would make any Top Fuel NHRA giggle with excitement.

Is there really any conversion from Thrust to HP? Only for specific examples.

Aerospaceweb.org | Ask Us - Convert Thrust to Horsepower

"Luckily, we do have access to data from a NASA report that does provide all the data we need to illustrate a sample case. The data is provided for a Boeing 747-200 cruising at Mach 0.9 at 40,000 ft (12,190 m). In this example, the aircraft's engines produce 55,145 lb (245,295 N) of thrust, only a quarter of its rated static thrust, to cruise at a velocity of 871 ft/s (265 m/s). Using the equations provided above, we calculate the power generated by the 747 to be 87,325 hp (65,100 kW)."

although at cruise a loaded 747 burns 1 gal/sec.

so, was this 747 in question, taxiing without chalks removed?

performing a fly by?

or at takeoff?

someone write Mythbusters.... they'd should have fun with this one.

Side note: As this is an election year, we all should be mindful of any statistical analysis which elicits a dramatic response in order to sway opinion and create a fervor of emotion to rally public opinion.
