To keep aircraft from crashing, they use high-speed chase/guide cars during take-offs and landings
The process is pretty simple: The Air Force buys fast and relatively inexpensive Detroit muscle and puts a highly trained pilot in the driver's seat. Those pilots then act as ground-based wingmen for the U-2s in the air, talking them through runway operations
Because of the speeds involved, the chase cars are usually high-performance cars. They wait at the end of the runway, and when the U-2 passes, they burn rubber to keep up, calling out altitude and wing attitude over the radio. When the airplane's main gear is roughly two feet over the tarmac, the pilot deploys several sets of spoilers and flaps to reduce lift and minimize wing drop, lowers the plane down, slows to a stop while balancing on the two center wheels, and then drops a wingtip to the ground (they have titanium skidplates for this purpose) and stops. The "pogo" wing landing gear that fell off on take-off are then reattached, and the U-2 taxis to its hangar. The addition of the chase cars all but eliminated serious landing accidents.

U-2S With SYERS notably different U-2S configuration, once again on the same aircraft. The nose seen in this picture is also elongated but it does not have the cooling scoop as seen on the ASARS equipped U-2. Instead, this nosecone houses the SYERS (Senior Year Electro Optical Reconnaissance System). This camera system, the U-2's primary optical sensor, can peer deep into enemy territory and possesses outstanding resolution. Upgrades to the sensor itself, leveraging breakthroughs in multi-spectral imaging, has vastly improved SYERS ability to see through smoke, light fog and transient weather. Additionally, it sees "more" than ever before as the camera is actually capable of operating in multiple bands of the optical spectrum. For instance, maybe a vehicle is concealed by camouflage netting and it is all but non existent when photographed using traditional optics. SYERS, with its additional infra-red capability, may pick up the heat signature from the vehicle's engine, effectively countering the enemy's attempt at concealing it. In addition to SYERS, in this configuration the U-2S is carrying panoramic cameras in its "Q Bay" below and behind the cockpit. These cameras can take high definition horizon to horizon images of anywhere the U-2 passes over or passes abreast of. There has been a concerted effort by the U-2 community to be able to lug around the SYERS and the ASARS-2 at the same time. Apparently a small fleet of U-2s are equipped with this capability and feature a massive bulge around the forward fuselage, behind the cockpit where the "Q-Bay" would be.

The huge radome on top of this Dragon Lady's spine is a satellite communications system known as either Senior Span or Senior Spur, depending on how the jet is configured. Senior Span is fitted to provide the conveyance of signals intelligence collection data beyond line of sight and around the globe. Senior Spur is used for transmitting other forms of data, including image intelligence and electronic intelligence gathered by the U-2's sensors. In its latest configuration, Senior Spur may also be able to transmit data over the horizon via Ku-band satellite that is being produced remotely from another source other than the U-2's sensors. In this function the aircraft would be working as a battlefield relay surrogate for other forces
