    ELP,

    Would find it unusual for a weapon to penetrate 6ft if it has an instantaneous fuze. Granted ‘instantaneous’ is a relative term :), but it is VERY fast.

    I’ll still stand by … “if there’s a crater, there’s a delay”

    wrt the ordnance possibly used….

    Most folks expect to see a crater when bombs are discussed. Not necessarily so (and probably most often not the case). Unless a delay is used there can be very little to no ‘crater’ effect. With an ‘instantaneous’ fuze (which is most typically used) even a 2000lb weapon makes just a very small depression in DIRT (max of a foot or two) much less when used on concrete (as in this example)

    Using delays are usually specified against particular target types to cause more cratering ‘effects’ (e.g. runways, roads). As the target here was an aircraft, probably ‘instantaneous’ fuzing was used.

    Yet then again…. Just a guess!!!!

    USAF JSF STOVL does nothing for CAS except provide some very limited PR value.

    I’ll admit I’m pretty stupid sometimes, but where does STOVL improve CAS???

    Ah… you’re closer to the ‘troops’ using partially useable runways and/or unprepared surfaces thus reducing transit time. Don’t think so… the most responsive CAS support will be provided by JSFs that have just come off the tanker and are sitting in ‘on-call’ CAS orbits. Having the JSF closer in terms of ‘bare basing’ does nothing more than greatly increase complexity of getting the gas, weapons, support equipment, etc etc to this ‘forward’ base.

    I’m still of the opinion the STOVL JSFs are only there to ensure the requirement for the ‘boats’ that go with them!!!!

    wrt the TBirds pic….

    This maneuver (as I recall) is performed flying 90deg to the show line towards the ‘audience’. Then the ‘cross over’ is performed wowing the crowd. This is done with ample nose to tail separation. Due to the orientation it appears that they almost collide (same can be said for this angle in the photo as well). If you looked at the 2 ship formation from the side it would look like they are flying in trail…

    As to the speedbrakes… must admit don’t know why they would be out unless pilot forgot to put them back in (it happens, no bells or alarms in the cockpit, other than a very small, hard to see indicator which one does not look at… esp in this situation). Th SB take a while to go in/out and as they appear to be fully deployed suspect they’ve been out at least a second or two prior to the picture. Pilot would be using more thrust than normal to overcome the added drag, but again might not notice unless power was at the max and he was still being left behind… Then you’d get a ‘clue’

    Moving on to the Viper video… Can’t speak to current recording systems as they may have moved on to new technology…. F-15 and F-16 both used 3/4 in video tape recorders. If the aircraft indeed crashes, sometimes portions of the tape survives. Wonder if they’ve moved on to using flash memory or other (not sure mini-disks would handle the g loads…) Costs may be competitive nowadays… But then again USAF is trying to save it’s nickels for the F/A-22…

    btw in my opinion the F-15 is not ‘out of control’ prior to the impact. Looks more like he’s trying to pull up and get out of the way…

    If you look closely you’ll notice that it starts out as a left to left pass, but the Viper driver looks like he misjudges the aspect and in an attempt to ‘deconflict flight paths’ turns left (very slightly) then stops. This unfortunately makes things even worse.

    For those interested, the flashing X in the Hud is meant as a warning for impending collision!!!

    Old numbers (by a couple of years)

    USAF Major (14 yrs or your most ‘experienced’ so to speak) $5000 base pay; plus $850 Fly pay per month. Doesn’t include any ‘bonuses’ etc.

    Mark

    btw No differences in what you fly in terms of pay 🙂 T-37 or F/A-22 same-same (also holds true for ‘status’, pilot, instructor, test, evaluation, etc etc)

    Welcome….

    You’ll enjoy the forum even though you have to wade thru some less-than-useful posts. Comes with the territory I guess!!

    Some VERY knowledgeable contributors (you’ll easily/soon sort them out). Get to see some nice pics now and then too!!

    Could be because it’s an AA-2c….

    http://vulcan09.com.ne.kr/AA-2_02.jpg

    which is quite a bit longer. Would make sense to have mix of IR and radar AAMs (the AA-8 and AA-2c). Still kind of ‘funky’ looking

    hmm…. low slow with AAA in area, bad news (ask the AH-64 Apaches at Najaf). Sometimes need to get down there, but you can pay a dear price if you do. Seems I recall most air losses to surface threats have been due to SHORAD (Manpads, smaller caliber AAA)

    DJ,

    Thanks for the pics…

    btw the AAM the ground crew is tinkering with is an AA-8.

    The other looks like an AA-2, but something not quite right about it (can’t figure out what, but the front end seems a bit odd)

    Anyway… Thanks Again

    F-4 had no monopoly on out of control issues…

    I would characterize the ‘6’ as being even worse wrt ‘spins’.

    At higher AOA, pilot must lay off the use of elevons for roll — (ailerons for ‘most’ anything else :)) Very nasty otherwise. Rudder was the control surface of choice when the angle of attack was getting up there.

    Once in a spin… very dicey on getting it out. It in particular liked to flat spin.

    Here’s some reading…

    Here’s some info on the ‘famous’ Six that ‘landed’ itself (sans pilot) subsequent to flat spin
