Okay so I'm reading the 9/11 Commisison Report and they're talking about how the two alert F-15's were scrammbled from Otis AFB.
My question is this: How long does it take to get a fighter off the ground (roughly)? I mean obviously the pilot wouldn't do an entire pre-flight, but can they really just jump in a go?
Just curious.
Thanks.

Air Defense alert jets are usually "cocked" at a certain response level (Alert 5/10/15/30), etc; the numbers denoting the minutes from call to launch expected of the jets. Cocked means that they're not only preflighted, but (if required), their systems are aligned, etc. So all that needs to be done, is for the crews to run out to the plane, which isn't far since the plane is parked in the "alert barn" which itself is connected to the living facilities for the crews, much like a large fire station; get engines started, get weapons pins and chocks pulled, and off they go.
So, if jets were on an alert 15 or 30 (fairly standard), they have that much time to get the word and get airborne.
There's many more available aircraft on a daily basis performing normal training than just NORADs alert birds. At Tyndall AFB, FL there is the standard few F-16s for air defense alert. But Tyndall also trains F-15C Eagle pilots, so there's three squadrons of F-15s (whose sole mission is air-air) with aircraft airborne at all hours of the day and night on training hops, and which can be easily-re-tasked per request of ATC if the situation warrants it, prior to higher approval (ie- in an ATC emergency).
Order of battle for Air Defense jets that day consisted of these units listed below. The top units are still AD units. The rest (F-16 units) were at one time dedicated to ADF, but have since converted to a "general purpose" mission (ie- dropping bombs), due to the post-cold war drawdown. These GP squadrons still maintain an alert det, but not all of the rest of their fighters sit armed/ready on the ramp dedicated to ADF.
Here's a further breakdown for those interested:
Dedicated ADF:
102 FW, Otis: F-15A/B
119 FW, Hector: F-16A/ADF
144 FW, Fresno: F-16A/ADF
148 FW, Duluth: F-16A/ADF
125 FW, Jacksonville, F-15A/B
General Purpose (former ADF):
120 FW, Great Falls: F-16C/D
142 FW, Portland: F-15A/B (air-air only)
147 FW, Ellington: F-16C/D
158 FW, Burlington: F-16C/D
