Taking a Tornado GR4 from RAF Marham to RAF Lossiemouth. Starts at 6000ft over Humberside (that's the bridge at 00:12). Then low level, around 420 knots with a min height of 250 feet, begins SE of the Lake District, approaching Lake Winder mere from South to North 01:30. Big turn so we check the 'under belly' at 01.13 half way around. At 02.56 we are passing Grasmere, put Latitude & Longtitude 54.452540, -3.017523 into google maps to see. Then following the A591 North. By 03:42 we are at the North end of Lake Thirlmere (54.556825, -3.070986). Passing Keswick at 04:01. The North end of Lake Bassenthwaite at 04:37, notice the wings sweeping from 45 deg, to 25 deg to help our turn performance, the condensation flow on the wing is pretty cool here. Next we zoom forward in location with 04:50 at the Western end of Loch Tummel in the Highlands of Scotland. Heading East we pass the Hydro site at 05:23 (google maps 56.720753 -3.825099), Pitlochry is under the nose at 05:32 and turning hard left to follow the A9 valley North West. More highlands before entering the narrow and tight Findhorn Valley at 09:08 and position 57.238458, -4.103893. Threading North East low in the valley ending low level around Findhorn Bridge at 10:09, we pulled up out of low level and commenced recovery to RAF Lossiemouth. The video from there onwards is of the way home in a different jet back to RAF Marham. Generally South East, before coasting out over the North Sea around St Andrews. We follow our rules and get sufficiently far away from the coast to avoid noise before starting a Supersonic run at low level. 500 knots to 600 knots takes about 8 seconds and from 600 to Mach 1 is another 7 seconds or so. Notice the Altimeter struggling to understand the Shockwave as we pass the sound barrier. It unwinds by about 2,000ft, showing us subterranean! Using about 600 kg of fuel per minute at this point. Normally it's about 60-70 kg per minute cruise at 420 knots at low level....gulp. So fuel dwindling, its time to zoom climb, slow down and medium level transit back to RAF Marham Norfolk (not shown).
