I seem to recall paying a couple hundred bucks at the time for that extra 8 meg module. Remember that potato king in Idaho, J.R. Simplot, who kept talking about buying more Micron?? On a sadder note, am I correct in assuming the shuttle reentry path was pretty close to where you reside in Texas??>>>> Some debris in Burlison, 33 miles SE of here Flight path must have been closer to here, maybe 10 miles or less> Jan asked me what I had dropped in the garage which would have been noise off the explosion I spent 4 years at Boeing working on a smaller but similar earlier craft the x-20 which they luckily cancelled . No tiles on it just some very expensive metal surfaces -some costing more than gold and cooled with inside fluids collectaire.com I flew the simulator at EAFB at Mach 4 at 150000 ft and crashed as did everyone else who tried it except experienced pilots. Tricky to control it in mighty thin air Columbia was going Mach 18, I heard. Tiles vary in size maybe 3 in to 8 inch and perhaps 3 inch thick ( I havent seen one) Very light and brittle like expanded volcanic ash . Could easily be damaged when booster insulation fell on the left wing at liftoff You can have have perhaps one or two entire tile missing if its in a less stressed area like the fuselage side, but the front of a wing at the root would be one of the worst places to lose a tile. The skin could then burn thru which is what I expect caused this problem If thats the case, somebody screwed up by not doing a space walk to look at that area and replace the tiles if damaged. But its hard to change the heavily scheduled work loads 28 flights on that bird in a space environment? Seems like far too many They need more money to buy new ones. Sad to lose people, can only say they left at the top of their game, doing what they liked. Sig
